The problem with a fellow GHer going for something and others holding off is that we don't know who the fellow GHer is on eBay, how much is his maximum bid, etc. For example, if I wanted to bid on this but held off to let Shawn get it, but someone else, a non-GHer outbid him, maybe I'd be willing to go even higher and still get it, but not take it away from Shawn being he was already out of it. That's fine if this all takes place early on and we're notified of it, but if it happens in the final seconds of the auction, there's no way to know what's going on and what's going to happen before it finishes.
Take the first one mentioned in this thread. MissleMike would have liked it, but didn't bid in hopes of letting someone here get it. But nobody spoke up to say they won it. It still sold for considerably less than MissleMike was prepared to go. So it appears MissleMike lost out for nothing. The same thing could happen on this one.
Being this is a common item, and lots and lots of non-GHer will also likely be interested in it, I don't really see the need to let someone here go for it. Odds are just as good that someone outside of GH will get it. If it's a rare item though and a few different GHers want it, I can see them discussing it via PM and talking about what their maximum bid would be and let whoever is willing to put in the highest bid go for it, to avoid making them pay more than they have to. For common items, I'd say it's probably better to just let the market due it's thing.
