Playstation 3?

I'm thinking about getting a PS3 but IDK if I should. I already have a 360 but I'm a huge fan of Playstation, I want blu-ray, and I LOVE the sixaxis control. But is it a waste of money since I have a 360? I really want it and I'm gonna pay for it wih my own money but I have a rep for being rich, and spoiled which I hate, and I don't want the PS3 to keep tha rep going. Shoud I get it (if I do it won't be for another month or 2)
