I tried Gixen after getting sick of being 'outsniped' trying to buy on ebay. If you can't beat 'em, join 'em I thought.
This simple, no fuss website makes the whole bidding process a lot easier. I now make sure I use gixen.com every time I want to buy of ebay.
There is a free service, but the 'premium' mirror service with enhanced features is only around $6 per year I think so hardly expensive. Given that this makes ebay buying easier, and helps you buy cheaper, it's probably worth anybody who buys of ebay to take up the gixen.com offer.
