There's a ton of threads about this already if you search the forums a bit. Short version is it depends on what you want out of a console (what type of games do you like? who do you play them with? do you value good controls? do you value good graphics? etc, etc). There's a lot of factors that go into the decision, other than just the cost.

Really, your best bet is just to search old threads -- this topic has been covered in ridiculous depth around here.
