It may be more expensive, but you get what you want and know what you have. Actually when the Otero was new, fully built the MSRP was $1,000, so I'll be in the ballpark.
I'm with you on the Avid BB7's. They are on my wish list, althought I'm watching a set of Juicy's on ebay right now. I may try to pick those up if the price in right. I'll put pictures up of the build along the way for those interested.
