You're right, the hobby can be pretty expensive. One way it gets expensive is when you spend a chunk of money on a cheapie "beginner" plane that doesn't fly too well and breaks before you really get to enjoy it.

Of the choices you list, one is sold out, one is a glider, and one is a Cub. Of these three, the Cub is probably your best bet. What might be even better, from this same supplier, is this one:

It's got a longer wingspan, it's a pusher (fewer busted props), and it looks to be sturdier than the cub.

In this price range, you really won't get much more than a toy. If you get up around the $150 range, you can get something a little better, like something from Hobby Zone.

Good luck flying, and good luck at Parris Island (and beyond).
