If I want something bad, I make sure I get it without overpaying using Gixen.
I had used a different snipper but it started charging. Gixen is currently free, this is June 2016. I sell on eBay as well, so being familiar with it, I know you can pay a lot more if you get in a real bidding war the last few minutes of an auction.
Gixen lets you skip the inflation and bids for you the last second it can. If your top offer was better than the other guys, you win.
