Maybe something like a Rickenbacker 325 '58 but, I'm not quite sure. Basically I'm looking for one that would be good mostly for rhythm. Maybe a beatles type sound. I would like a rickenbacker but, they are way to expensive.
Dude just keep saving until you can get a rickenbacker. Getting the original is the best.
It's hard to find a replacement for a Rick. First, they're all-maple construction, something not a lot of guitars have. Second, they have their own unique pickups. You might be able to get a custom chambered body built and get a set of Rick pickups. You might get close that way.

^ that isn't always the case.

Try out a Italia Rimini, they're aimed at Ricky's but are much cheaper. They even have a 12 string model if you're after that.

EDIT: the first point was directed and nan0
