Mesaflyer,
Here is a link to the Skyraider Mach II:

This is an ideal second plane for you. Like yourself, I taught myself how to fly and I figured I was ready for the higher end of performance (and looks) when moving up from my trainer. I ended up with a bunch of scrap balsa and a lot less money. Try to progress slowly, and when you have really mastered the plane you have, then move up.
The Skyraider is an excellent choice because it is a very capable and sturdy plane. IMO, it has the ugliest color scheme imaginable, but that is redeemed by the $69.00 price tag. When you crash it, it doesn't hurt too much
