I bought mine from Newyorkbarbells, because they had the most attatchments with the two pulley system and the leg press that was heavy duty for a non-commercial price. I did notice that other places have some things that are better, but you have to balance it out. most cages will run about $500.
If your budget is only 5bills for weights and bench and cage, then you will have to hit up a used store, craigs, or something like that... good luck and let us know how it goes.
