the largest group buy i know of has been through florida inboards seasonally in the spring, and just ended i believe. jody from FI said he's not doing them anymore due to some bad apples (jet boat owners, i'm guessing) being jerks about the whole thing. you could try calling and see if you can still get in on it--my buddy got PP stargazer for his nautique for that GB price of $1048 i think. otherwise, the best price he was able to get elsewhere was $1099.
the other option is ridesteady. everyone seems to shy away because they're not as big as perfect pass, but i wouldn't hesitate to buy them if i didn't already have PP. they're around $1100 but include some features that PP doesn't. and $100 off if you do documentation of your install. hope that helps.
