Buchanan's are good but I would also like to know if there are other rim or spoke places to purchase from.
I explored this a few years ago. After several successful wheel episodes using Bucky's I went off looking for someplace less expensive. I googled everything I could think of. Found a place in NJ that had a similar selection, slightly less $$. Ordered a rim and spokes. It came a few weeks later than expected. The return address on the box was...Bucky's in CA! The spokes came in a bag, seperate shipment, with an insert, instructions, on Bucky's letterhead. So I figured I got it from Bucky's, with poorer service.
A followup call a few months later indicated the NJ outfit was out of business.
I found one other place, full service, in N CA. They catered to dirt bikes but said they could do my stuff also. But by then I didn't need them.
So, google away, and let us know what you find.
I think they've got the market tied up. You'll find a better deal here and there for this or that. But for full service, full product line, I think they are it.
