I take a K2 ahaed of a K1000 any day. I had the K1000, only Pentax I sold again, it's fame is hard to understand, not a bad camera, but when there are bigger brothers that has the important feater of DOF preview (KM, KX, K2) that goes for less... But this is good for you. Let people buy K1000 for overprice and pick up a KM/KX/K2 yourself for a good price.
I have a KX and love it. Would like a K2 also, the auto function would come in handy. But I think I would miss the judas window for the apperture in the viewfinder (which KX has, but not K2). K2DMD has the apperture window, but it is harder to get hold of.
Some complain about the odd asa-setting (iso for you young fellows), but others says you get used to it. I have not handled it long enough to have an oppinion, but I would be prepared to give it a chance if I could get hold on a working K2DMD. How hard is it go get hold of a K2DMD with a working driver?
These were shot with the KX (black version) and the SMC Pentax 135/2.5, except the last one which was with the M28/2.8, during last years x-mas shopping:
