I did my primary training at my local airport in a 152 and enjoyed it very much. It is slow so you can get used to the reaction time it takes to fly an airplane. Also, it is incredibly easy to fly, and especially land. Right now I'm flying 172s and Socata Trinidads for instrument training at my college, the University of Dubuque. The 172 is also very easy to fly, and a very good instrument trainers. The Trinidad is a little more airplane, but still fun to fly. I've never flown a Diamond, but low wing airplanes do tend to heat up more than high wing aircraft. Hope this helps.
