The folks over at Neuvation Cycling are having an excellent sale on their very popular wheels. At $299, I think that the R28 SL3 is a killer deal. These compare favorably to a Ksyrium ES, but go for $500 less.

Neuvation has a very high rating across the board from the readers at Road Bike Review and their customer service is often cited as some of the best in the industry.
Right now, they are also having a sale on ceramic bearing upgrades. Ceramic bearing kits for their wheels typically run $100, but right now they are $35 to $60 with the purchase of a wheelset.
