I have managed to get a Pentax K20D for £185 - should be picking it up on Wed. Went over and had a look at it, seems to be working fine, so thought Id go for it, bit more than I wanted to spend, but it was such a bargain, I couldn't resist 
It comes with the 18-55 kit lens, so bearing in mind I can use all the old Pentax glass, what would be the first lens I should get for my new toy..
At the moment, Im thinking a macro lens or a prime, but not sure so thought Id see if anyone here knew some good old lenses that I should keep an eye out for?
Choosing the camera seems the easy part now that I have seen just how many lenses are out there..
