Much like the dibs system. I only ever place dibs when I'm awaiting pictures or a better discription, otherwise I can pay up immediately. I hate it when someone says "Ooh that looks nice... I've never seen one of those before, but dibs... Oh and I'll pay you in a month." Then someone else comes along one minute later, but has been looking for one of these for an eternity and has the money for it right now! But that doesn't matter, as someone else placed "dibs" a minute before hand!

I say just stick to ebay methods with ebay listings, but just don't go posting up auctions on the forum to attract the masses, unless it's your auction.
