Hi Bob, the US Avant was available until I think 2005-ish . . . the same chassis was used in BeoVision 5 (plasma) and the BeoSystem 1 (external sound & picture processor), so I'm not sure exactly how production resources were allocated to these three products at the end. BTW, the Avant is the best of this generation in terms of picture quality.
But if anybody's looking for one, I'd certainly stay away from Ebay - they're expensive to service, and 2K is more than I'd pay on Ebay for one. Rumor has it that Bang & Olufsen Newberry Street in Boston has "a bunch" of Avants, so I'd start there.
