You should also take a look at SPADs at

You still have to buy an engine and radio. SPADs are a little different to build, but it isn't hard. And the cost is hard to beat. There are also some guys selling SPAD ARFs that are still quite a bit cheaper than the typical .40 sized trainer.

Electric park fliers like the firebird are also options, though you should ask around about a specific one (as you did, but try the electric forums), as some of them don't fly well, espeically for a beginner.

I trimmed out a firebird for a guy who showed up at the club field after he had problems flying it on his own at the local park. I got it going for him easily enough. The rudder-throttle planes fly ok as long as the thrust line and wing incidence is correct. (his was off a hair, making it impossible to fly).
