Joe,
Last year Proflight sold their 65 lb coated new lead bars for about $50 each at the boat show. And, on the last day of the show they were blowing them out for $35 each - I got 6 - I guess they did not want to ship them back.
The same new lead uncoated can be purchased for $0.50/lb at ALCO in San Leandro (just south of the Oakland Airport off of 880).
