I was thinking of getting the wife a K2000 - mebbe even the limited edition white one!
I shoot a K20D - got it for Xmas what a freaking camera - I absolutely LOVE it, and especially that I can use 20-30-year old lenses on it, no adapter required. One of my mainstays is a fully manual (zoom, focus, and aperture) Vivital 70-150mm lens with Macro!
You can usually find the Pentax SMC-F 28-80 pretty cheap, on the order of $20-30 on fleaBay, and Adorama / B&H used departments. keh.com also has some cheap older lenses.
What telephoto range were you thinking of?
If you have a Ritz Camera / Wolf Camera store nearby, they had a Sigma dual-lens kit on clearance a couple months back. Model number for the kit is I think V9945 - check and see if you can find one. Decent enough for the $150 they were asking for both.
