i had a similar situation with a "roland" electronic accordion, years ago. the price was good--about 2k less than retail. the transaction was done, but when i tried to replace a missing cord through the mfgr, i found out that this was a stolen instrument, being sold by a shill--a foreign student, doing a favor for a friend. ended up in conversation with police in new york, and boston, and finally getting my money back from this kid's father (in the mideast), who wanted to avoid scandal. such a deal! not!! i've steered clear of big purchases online, ever since. i got lucky. most folks don't.
