Answering might well be no joke at all, and is thoroughly not recommended. Unless you want a virus-infested computer, that is....

What about the new EyeFi SD cards? New Pentax compacts are already compatible with this new technology.

Prices are so variable across the suppliers at the moment that I think you'de need to give a bit more detail, but to be honest value is not only price.

There are many other things such as backup, quality, reliability, handling, etc. that contribute to the overall value to the buyer. Just buying on price means cheapest is best, but we know that isn't true.

It's mostly down to mechanical design (the Bessamatic was a complex bit of engineering) and the laws of optics. As lenses focus closer, the light fall off changes the effective aperture. The aperture value holds well down to about 1:10, which is why 50mm lenses focus down to around 50cm (actaully 45cm for Pentax) - the design gets more awkward if you want to focus closer, and the price goes up.

Modern zooms seem to happily break all these optical rules - they don't really of course but new technology has found new solutions.

Incidentally, the camera + lens is now on eBay at a BIN price higher than the offer here.

You can actually focus quite close with the 18-55 kit lens, around 1:2,9 I at least found it close enough.
Quite so. We are very spoilt these days. I once had a Voigtlander Dynarex 135mm lens for Bessamatic. Very nicely made, but close focusing was 13.5 feet! One reason the German camera industry started to lose out to the Japanese.

Sorry I have to decline again, but it is a package. The buyer always has the option to sell on any unwanted parts of the deal.

Lowest price is £350 collected, as mentioned, or £375 shipped anywhere in the world with full insurance. On the UK this means Special Delivery, which is not cheap for something of this weight.

You shouldn't be using Nicads. NiMH rechargeables work well, as to Lithium cells. Alkaline are not recommended. Believe the instruction manual!

eBay would be a good choice, cost might be less than £10.

Other than that any photographic supplier will stock close up lenses in a variety of strengths. They will be marked +1, +2, etc. up to probably +10. Sets are often +1, +2 and +4 which gives a combination of options when they are used together up to +7. I have such a set on eBay at the moment, Vivitar branded in 49mm.

Start with a set or maybe a +1 and +2 and that will give you the option of a +3 when used together. Always put the strongest nearest the lens.

One very inexpensive solution is to use a close up lens with your 50-200mm lens. This screws into the front of the lens just like a filter and enables you to focus closer. Stopped down to f11 you will get excellent results.

Use a tripod to ensure correct focus and no camera shake.
