dont go to bob jane, or big places like that, the people that will do the best deal are your local small tyre shops, they are run by 1 guy, and they will knock off a lot to get the sale, I paid $1700 for my rims and tyres, and bob jane quoted $2400 for the same set.
When i checked around, most small shops were around the same price, they may not have the big display, but have access to the suppliers, so go in to a big shop, pick the wheels, and buy them from a small shop.
easy, and $2000 will get you a good set, with good tyres.
