personnal favorite is smartsnipe but i usually set all all three just to be on the safe side. easy to setup its all done on their website so no spyware and shit like that on your computer. all have free service which is enough if u are like me who only use ebay once in a blue moon but you have an addiction to buying junk on ebay they offer pay service too that let you do more auctions
