I in the past have paid in the $250 to $350 range. $800 is way out of line.I did! Haha it makes me feel better about paying $475 total for my LI, GRWs, 106 mower, sulky, parts tractor, and circular saw blade and guard. One of the complete gearbox/saw/guard assemblies actually sold for $270 on eBay last week! I'm still not sure it's worth that, but whatever... I won't complain.
I think the GRW parts seller is going to be sitting on those a while, or he'll lower his prices.
