Just got my SB from eBay. I guy sells both the 451A and 451. I talked to him last night. He says he doesn't have all his items listed on eBay all the time. But if you e-mail him, and can get one up. His e-mail is sale@partsexporter.com He charges $280 + $20 shipping. Took 8 days from when i ordered to when i received. I recommend this guy. His name on eBay is partsexporter. He just had 3 for sale last week, and they are all sold. so just e-mail him and he can set up more. Have fun.
