allen i was thinking the same as you junk the whole spider gear setup for a true locker. my contact was drexler themselves in europe and the quote is 1600 eruo (approx 2k$) but from what i can tell its the best on the market and would cure any issues we are having. thats a 1 time buy no idea what a group buy could do.
was just looking for something in case allens wavetrac falls thru. p/g is my last resort as its not a true locker and doesnt cure the weak link issues
