The istD didn't have scene modes McGregNi

As for the original post, it depends on whether or not you want to keep the two operating dials and/or the option of adding a battery grip, also did you find the top plate LCD useful?

The K50 is reasonably priced (new) will give you all of the istD operating modes (and more) it has twin operating dials but lacks the top plate LCD and wont take a battery grip.

Models after that tend to get expensive unless you buy second hand, K7 K5 K3 all have twin dials, top plate LCD and take a grip, if you buying secondhand go for the K5 over the K7 as the 5 is a better model and I can't see there been much difference in price.

Other used (older) models with the same features as the istD would be the K10D and the K20D but both are much larger cameras and like the istD are becoming a little dated.

Depends what your budget is really.

EDIT: Sorry should have said, don't worry about menu or button layout, you won't get anything which matches the istD exactly but they will all be quite instinctive to use and you'd soon get used to a replacement.

Totally have to disagree with stu on the K5, it's leaps and bounds better than the K20D

Another thumbs up for Alan Marlow, he made a nice job of cleaning my Bigma.

Sorry, I couldn't make it either.

Trying to get out with the K3II but things keep getting in the way, had it almost 5 months and only taken a few dozen frames

Got Whitby Goth in a couple of weeks so finally a chance to give it some use

Nice one,
but I hope you look after your cameras better than the rest of your tools

I can't see that worn paint and peeling rubber from the grip should constitute "poor condition" my insurance company initially refused to replace my K10D with the K3 on the basis that the K3 was marketed as a Professional camera and the K10D wasn't.

If the K3 is indeed a pro-spec camera then Ricoh should accept it may suffer a fair bit of cosmetic abuse without it affecting the warranty.

I think your having us on, you've cloned one in from a teddy bear

The K1 will automatically crop the image when a DA lens is attached (unless told otherwise via the menu) so it will still give you the 1.5 crop factor and an image the same size as from an APS-C sensor body, If you disable this in the camera settings the lens will give you a full frame image as per its focal length (not cropped) however there may be vignetting round the outer edges of the frame where the DA lenses image circle doesn't fully cover the sensor.

I think this has been a common problem with just about every DSLR Pentax has released the battery level indicator just doesn't indicate battery level very well. I've had this with the K10D, K20D, K5 and expect to experience it with the K3II, the only model which seemed OK to me was the *istD, perhaps it's something to do with the battery.

It would be interesting to hear from anyone who's used AA's in the battery grips to see if they have the same problem.

Is it a hotshoe attachment so you can mount the camera upside down
