There will be as many opinions as you want on this question, so it will be a combination of all of the advice you get here. The order that I did was:
1. Avistar (trainer)
2. 4*60 (low wing and easy to fly)
3. Ultra Stick 60 (I love the speed and and its aerobatic ability)
4. SIG Something Extra (building the kit now.)
5. I have more planes on my wish list to than I have money to
buy them. I am considering the following: Excite 90,
shoestring, and every other one I like. oops...I am getting off
track here.

Listen to everyone, talk to your flying friends, and take everyone's advice into account.

BTW: I still fly my Avistar when I just want to relax.
