Just as a counterpoint, I was part of the group buy from hell with 18Racing, and they handled themselves very poorly IMO. They failed to meet their promised delivery date by several months, to the point that I gave up and bought something else. I ended up selling the Rotas before they ever shipped, and for less than I had paid (it was a non-refundable custom order). 18Racing sent them to the wrong place when they finally did ship (I think all the wheels in the buy ended up going to the guy who organized it). Then I had to deal with an angry buyer who didn't get his wheels, which I was powerless to fix. It really sucked all around, and I wish I could have back the hours I spent on hold with them trying to figure out what was going on, and fixing all the billing and shipping screwups they made. I spent most of my lunchbreaks for about a month just trying to get it all straightened out.
