Unless they are giving the turbo away for free, don't waste your money.
You can get a brand new Master Power turbo from Brazil based on Garrett parts and sizes, from a ISO 9001/2000 company. (That means they can bid on and build OEM quality parts, and they have a pretty good reputation in the market as well.)
Here is a good example.
I just bought a Master Power T70 turbo for about 600.00 shipped to my door. (Try ebay, look for Miketurbo.)
It's every bit as nice as the similar turbo's I've seen for 2x the price, and I really can't say they are better in any way actually.
Another example is a Tarus handgun. You can buy the Beretta and pay 600+ for your 9mm self defense weapon, or you can buy the Tarus copy of the same weapon built in Brazil of the exact same gun with a few minor changes, and pay about 1/2. (BTW, my Tarus PT92 has cycled over 2000 rounds with zero problems, and I have nice rubber grips and other aftermarket stuff on there as they are very popular.)
