I think any snipeware, if there is such a thing, would be prone to the same weakness as live sniping, ie there is always the risk that your bid gets delayed in these final few seconds between your computer and e-bay and you get a message back to say the item is no longer available. Then when you check you find it sold for less than your bid. I used to snipe manually but I have learned the hard way that if I really want something far better to place my maximum bid well in advance, rather than see the item go to someone else for less than I would have paid, because my bid got delayed on the internet. That bid remains a secret unless/until it is topped so I can't really see any advantage in sniping. My advice would be to place your maximum bid before you go out, then check when you come back home to see if you won.
