Shift kits?

B&M transpak shift kits have always worked well for me in the past and I've only heard good things about Transgo.....
I'm considering a kit for my 700r4 off of ebay by a company called Trutech because it provides new accumulator pistons and springs and corvette style servo piston.....

I'm wondering if anyone has any info (good or bad) about Trutech and their products.
Their ebay reputation looks good, but I'm concerned about more than just a transaction!

IMO............I've always stuck with the brand name products for specific applications, especially a trans.
