If budget is an issue, & it sounds like it might be, then take a look at the classified here on RCU. There is usually some Trainers for sale as guys progress on to hotter planes. There is also usually some garage sell adds where you might find a field box with most of the goodies you'll need. Someone's allways retiring the hobby for one reason or another anyway it's worth taking a look. You can refine your search to go straight to the Trainers, unless you wanna drool all over the nice stuff too

Good luck.
