Once you guys get the hang out these check out some bigger planes.
I've been building and flying them for about 3 years. It's loads of fun.
It's easy to blow a lot of money on it though. I've spent around $15k total. I almost regret it. But I don't.

You can get beginner models with the radio, etc, nearly all assembled, for around $200.
