The other name that comes to mind is Jamie Passon, Passon Performance. The decision may be based on shipping costs.
One thing to ask about is where the bearings came from. US made bearings are 3-4 times as expensive as foreign sourced bearings, but are significantly better.
While Brewer's Performance didnt rebuild my 833, just about everything I needed for the conversion came from them. Wonderful guys, and I cannot recommend them enough.
