The eBay auctions are outrageous
What?! Two empegs sold for $352 and $363 on ebay on Dec.28th. I don't recall ever seeing prices that low. I guess that Christmas kept bidders away though - a 10GB sold for $510 on Dec.31st.
ebay is possibly the definitive pricing guide for the empeg. With only ~4000 units worldwide, empeg pricing is very much about supply & demand, which certainly fluctuates.
$375 is hopeful, but certainly possible if you're patient and lucky enough. I think that another $50 would increase your chances considerably though.
Good luck.
