Always Turbonetics, A'PEXI, Blitz, Trust and a bunch more if you just have a thing against Garrett
But as far as ebay Turbos think of it this way, 600 bucks for the Turbo on the off chance its one of decent build. But if its like most of them than $600 or the turbo and if it shits itself well enough a wallet killing amount for the rebuild and then another Turbo.
