I use two progs - I use both at the same time on important items - avoids failed bids ( time outs, time diff etc)
auctionsniper - has intergrated photos, saves time
esnipe has the best record, used it for 7 years, never a missed snipe - does cost, but you get what you pay for. A missed bid on an important item, can be repayed several times over by using a reliable prog, cheers
