get what you pay for
never seen them so not judging quality
why buy copy when you buy right, once only!
i paid £950 off ebay for a Turbonetics T61 i had on one of my saffs, lasted 3 weeks at 34psi, sent it for rebuild and it was sent back with pics of other replica turbos and pics of genuine Turbonetics one, nothing like it internaly and i was £2200 down by the time i bought a pukka one and the paper weight
i would be very wary and hopefully some more reviews from folk that have used them
what about trying some Evo forums of supra forums?
