Quad 57 refurbishers - who's the best?

What's the best company for refurbishing Quad 57s and/or selling refurbished Quad 57s?

Quads Unlimited. Wayne PK. He is the best.
Apparently so, on this continent anyway.
Where the Quads strength lie not much even today can start to come close.
Thanks for the info!
http://theanalogstore.com/ does a really nice job.
where are you? mailing quads is hard.
Mothra, I don't have the quads right now. I'm looking for a pair and wondering whether to buy already refurbished or take a chance on a used pair and have them sent directly from the seller to the refurbisher.
well, bill thallman here in the dc/va/md area is good. he may order parts from people but he also knows quads really well. I think wayne is good, maybe on the more expensive side?

sheldon stokes is a great resource but he may be out of refurbishing because he is too busy. He's a very thorough and smart guy.
