Ebay addicts get their fix from sniping. There are a number of sites which offer sniping services and a few "bid watchers" which will place your own last second bid. For many, it provides a "high" superior to Texas Hold-em.

I tried out a Java version tonight and snagged a couple of cable modems at about 30% below average sale price. The author is a little peeved at people who sell his program on Ebay which he gives away for free. Last September's version still works (Ebay changes their system occasionally).

You can download JBidwatcher here. You will need the Java JRE and be sure to read the instructions (RTFM).
