Sounds like you may be underestimating the comercial value...
I bid in two ways; for something that might be cool to have but is not a big deal, I'll wait as long as possible and then bid whtever change I'm willing to blow.
For something I REALLY want, I take what I think it may be worth and add what it's worth to me (ie- how f#*king bad do I want it?). Then I add $6.52, wait as long as I can, and bid. If someone still beats me, I assume they're stupid or crazy and you can't win against people like that. Sniping or not, if you have the highest bid, you win.
I read on a review of spiper programs that names with the word "hammer" in it could be viruses. So watch out.
Unless I'm wrong.
