RichardDan - I would be careful. I believe that ebay has an option where the seller can end the auction early and sell to the highest bidder. I do not know if this still applies when the high bid has not yet met the reserve, but I would not want to find out.
If the higher bids are shill, then the seller could potentially retract them until you are the high bidder again and then end the auction to sell to you.
