Never shot, nor do I know anyone that shoots Pentax. I took a quick look at the K7 and I don't see where it's specs are far better than the D90, but that's me. The Pentax does have in camera stabilization (although some say having it in the lens is better). But I would say to look at the system, you aren't buying just a camera. Nikon certainly has more lenses. This may or may not be a factor provided Pentax has the lenses you need. I don't know about the Pentax flash system, but I know I prefer Nikon's flash system over Canon's (the only other system I have used). What is it about the D60 you are now trying to upgrade? In other words, what's prompting the you to consider Pentax?
