I bought a Pentax ist DL second hand and wish now I hadn't. It broke down - will take photos but won't transfer them to the card, so it's a PC or motherboard problem. Swapping it would be easy if one existed, but Pentax have stopped supporting older DSLRs. If and I say, if I buy another DSLR it will be a current model and I'll try to get it with the longest warranty possible. Someone said earlier planned obsolescence - they're right. I have little confidence in shelling out hundreds on a DSLR if several years down the line the manufacturer stops supporting it to the extent that if it gets a fault, it's effectively a doorstop. I dug out my old SFXn, shoved a 35mm film in it and it carries on like a tractor, and if it fails, the replacement cost is in the 10s of pounds not hundreds. 35mm is cheap, D&P straight to CD also not that pricey. Maybe I'll get another DSLR in the future, maybe not. They're far too expensive to be obsolete after just a few years.
