Hello awwheatley. Buying a slr is an exciting step. I am not to familiar with both cameras you listed but I can say this. Just remember that when you buy a DSLR your buying a system, which means all lenses will only work for the brand of your camera. I believe the Pentax K2000 is geared more to beginners, I think it has a dedicated help button to help you get through all the technical stuff. However I think you will be happy with any camera you choose. Best of luck....
