Excercise Equipment

Hey guys, I live in an apartment so my space is limited. I'm looking for the best bang for my buck. I am thinking elliptical machine, but if there's something else out there that is just awesome... feel free to recommend it.

But does anyone know the best place to find a good deal on ellipticals? I'd like to stay under $1,000. I'd rather not even spend that much, but I need to get in better shape and do something. Anyone have any experience with these things? And how hard are they to put together?

If you have any specific models or links to places to buy these things... feel free to share whatever input you have. Thanks!
