I have found only one use for the old Zinsco panels. The cans (with the addition of a few screws) make good Jboxes.
Forget the Chinese breaker ... been there, done that. It lasted about 8 months, tripped and wouldn't reset. The "Boneyard" in Alexandria, VA sells "reconditioned" Zinscos (if you want the telco, drop me an email). I believe their definition of "reconditioned" is, as gfretwell says, washed and dried.
My vote would be to get one large panel and sell the Zinsco guts on eBay.
