Extra note - that embedded JPG is very useful for tying in the colours of the camera's RAW converter to the PC one. When you use RAW+ (in the K10D/K20D) then the separate JPG is saved with the specified quality. But the embedded still has the camera's RAW processing applied - colour, sharpness, etc.

So, from a long-term point of view, I would see it something like this:
K20D now for £500, sell for £300 in 6 months. (loss of £200)
K7D now for £1200(?), available for £700 in 6 months. (£500 cheaper)
So, if you bought a K20D and traded up in 6 months then you're still £300 up That'll get you most of a DA* lens
Seriously consider the cost of the glass For example, the DA*50-135 is utterly sublime. Yes, the K7 will probably be better in some respects - but I'm not sure by just how much
The Pentax digital glass though is well worth shelling out for (e.g. DA*50-135, DA17-70, DA12-24, FA50/1.4 etc).
Your other option is to consider the slower and older cameras like the *ist-D and *ist-Ds. You can pick them up for around £200 with a kit lens. I still have the *ist-D that I paid around £1100 for With good glass it can still take seriously good images (and I mean seriously good ) Very tiny size, still packed with features, and very configurable. The *ist-D & *ist-Ds are TTL flash compatible too, and work very well with manual focus lenses. That way you'll get to try all your old LX glass.
Let us know your location - maybe there's a Pentax User who could let you try the various dSLRs
I'm not knocking the K7, but I'm just pointing out that one of the older bodies may cover 80% of your photographic needs for not much outlay

The RAW format is not just a binary dump of the sensor data. There is a huge amount of EXIF data, plus the embedded JPG.
Check out http://thomer.com/howtos/embedded_jpg.html
and http://www.rawworkflow.com/rawworkflowcom-download-page/
Can't remember off-hand what size or quality the PEF embedded JPG is - but it's in there
If you want to really find out how the PEF format works, then check out the DCraw source code (from Dave Coffin) - it's fairly well laid out, but you have to pick through all the other RAW formats too.

Both very good - especially if you use Ed Hamrick's "VueScan" software. The software makes all the difference - especially for batch scanning slides

If you are able to do so take a look at the capacitors like shim suggests. If it is built in a way that you can give it a go with a soldering iron it could very well be a cheap fix to this problem.
Have you ever touched a flashgun capacitor before?? It's not funny at all

Thank you Matt, most useful and informative, how do you rate the Wiziwyg? most colour calibrators I have seen are quite expensive IE. Colour Monkey
Probably the cheapest device is a Pantone Huey. (Personally I'd use it with the ArygllCMS system - which is superb, but requires command line work!). Colour Monkey has a broader market, IIRC, such as profiling printers and grabbing colour references from physical items (like fabric & walls).

the moment came to transfer them for editing
i) Copying 2Gb takes a while - and this will be the same time whether it's 2Gb of JPG or 2Gb of PEF or 2Gb of DNG. I use the Sandisk Extreme III card reader - fastest card reader I have.
ii) Converting RAW into JPG/TIFF does take a while. You have more flexibility, and more options for noise reduction & sharpening. Some RAW converters are achingly slow, others are faster. Lightroom and Capture One provide background processing - so you can be working on the next shot(s) while the previous one is being processed. Other converters work in a batch mode (like Silkypix). I would reckon around 30 seconds per image for a K20D RAW file (even on a fast machine).
Do be aware that there is an embedded JPG image inside each RAW file. That can be extracted using a stand-alone tool.
If JPG suits your needs, then yes, without a doubt it will always be faster.
If you want to eek the greatest amount of detail (both sharpness and tone) then RAW is definitely the way to go.
I would say - consider using RAW if you have reached a "ceiling" in your image processing and expectations. RAW heightens the bar but at the cost of data storage and time If you are not feeling limited by JPG - then continue using it!!
HTH!

(Much like a car odometer would do)

So that's *ist-D, *ist-DS, K10D, K20D (if I haven't missed any!)
LCE Group have some e.g. K10D £280
...and you could always phone Chris at SRS Microsystems - I'm sure he gets second hand ones too
