What's a good 360 to ps3 controller converter?

im trying to get my 360 te stick to run on the ps3.

i just learned recently that these things exist, my question is what is the best one available? and how much would it cost. thanks.

have you looked into getting it dual modded?

im trying to save money, i saw a few for around 50-60, dual modding is a bit much for me atm
