Would it be worth it?

The PS3 isn't going anywhere. I would pick up a few Wii/DS games and save the rest. Maybe you can try to get a job this summer to get some money to put towards a PS3 and some games?

I really don't see the point in investing in second console unless you can buy 4 or 5 games for it. With limited funds, you are probably better off expanding your Wii/DS libraries.
