Welcome to this hobby. It is a hobby that you can have a lot of fun with, meet a lot of great guys that are more than willing to help you on any decisions you want to make. I am also Sorry Sig lost the trade deal, maybe they will regain it, who know's? They made some of the best trainers out there.
A friend of mine bought the Avistar and it flew great. Most any high wing trainer will get you going but ask the guys at your field or club what they recommend. My personal preferenceare Nitro powered planes, but there many decent electric's out there too. It just comes down on what type of plane you want to get started with. Good luck on what ever you choose and fly Safe.
