I'm looking for eBay bid sniping software that will run on WinXP, preferably freeware if possible. After a bit of Googling around I can see there's lots out there but I've become somewhat nervous of grabbing something and plugging in my eBay logon credentials.

Can anyone here suggest/recommend something based upon 1st or 3rd party experiences please?

I do have an account with Bidnapper.com but that costs (I think) $1.50 per successful snipe. It's good but for cheap things it's not always cost effective.
