bogus auction for Altair system on eBay

I exchanged several emails today with an eBay seller offering an Altair system with disk drive for a starting bid of $2 in a one-day auction. This is a bogus offer - I became uneasy when the seller solicited an offline offer in response to a query about shipping but insisted on payment through Western Union rather than PayPal, even though the orginal auction listed PayPal as a preferred option. It is interesting to note that the auction I saw this morning (offered by seller DOCHANDS) was cancelled by eBay almost immediately but the _identical_ auction (same pictures and extensive text) is currently (2/21/06 @ 11:31 pm) being offered by two different sellers - as auction 6038449898 by GUNDAN760 and as auction 6038549050 by SHARISINA. It looks like the "seller" is hijacking legitimate eBay accounts to use as bogus fronts for his dealings.
