I see this kind of question too many times...

Whats the rush, just enjoy learning to fly.

You probably won't believe this, but a better flying plane will not make you a better pilot, just the opposite, its more responsive, which makes it easier to perform manuevers.

I was getting ready to buy my second plane when a fellow club member (who happens to be a very good pilot) asked me why. Of course I said that I was ready to move up, I did all I could do with the trainer. Then, he asked me to show him what I could do.I took it up, flew inverted, hammerheads, rolls, etc.. then he took control of my LT-40 and began to do some rolling circles, rolling loops, etc..

At that point I decided that there is still life in the old trainer, flew the snot out of it (could even hand it on the prop, knife edge still kinda sucks tho), then I bought what most people would consider a third plane (no problem, my skills are adequate).
