RBFoley,
There are "degrees" of airplanes when starting out in this hobby. I think you're just beginning to see that.

You can buy some "2 channel trainers" for as little as $60. Chances are they won't fly, or if they do, they'll fly poorly.

Then you have the 3 channel Aerobird, and others like it. They're okay if it's all you can afford, or all you want to commit to.

Top of the list is probably a .40 size, glow fuel powered, 4 channel trainer. $400 to $450 for plane, engine, radio equipment and the extra stuff you'll need to assemble and run it. You absolutely should also join the AMA ($58) and a local RC club ($25 to $100), and have an instructor (Free) teach you, because these are the least likely to survive learning on your own

If you find that you enjoy RC flying, chances are you will eventually get to "glow powered" aircraft, or larger "electrics" which also cost in the $400 range.

Good luck and welcome!
