I'm suspicious of some of the so-called "live" auctions. One of the more well known collectors used to sell on regular Ebay auctions and has now gone "live". Good way to add xtra profit to the sale in the form of the buyers premium, and without declaring a reserve that would increase the seller's Ebay fees, it seems possible to void a low bidding auction by declaring it was "won" by some anonymous live bidder as opposed to an internet one.
It's already bad enough trying to score a good deal on Ebay thanks to all the rookie knotheads that keep bidding up items because they think that they have to be top bidder throughout the duration of the auction instead of just the end.
I suppose if you have more cents than sense, "live" internet auctions are just fine...
