When mine went i couldn't get a Metal one but I got the white plastic one.. Didn't have any problems since.
If you have any Mech. ability do it yourself its like a 30min job. 8 bolts IIRC and out and back in its really easy hardest part is making sure all the plastic is out. Mine broke in 3 big peices. But if you can do it yourself it will save you alot of money
