A little bigger huh... well there's the Esky Honey Bee FP, it's closer to 400 size. You'll most likely be shopping for parts online but they are available. I don't have any personal experience with it but from what I've read it's another good one, you may wanna do some quick googling to see if it's more up your alley.

On a somewhat related note, I'd highly recomend looking into an innexpensive flight sim program like Clearview for example. It'll use your existing Tx with a USB adapter (purchased seperatly, about $20) as the input device and will help you to practice the basic orientation skills, and take a crack at the more advanced models to see if you're ready. Real Flight is well known and comes with it's own Tx input device but it's spendy.
