If your picture is hanging on eBay's 'Favorite Customers of All Time' award wall, this eBay Watcher widget might be just for you. As a powerhouse eBay monitoring tool, this widget has it all: up to three items can be watched at once, audio feedback for price changes and auction ending, Growl notifications, automatic refreshing at user-specified intervals, localized display labels for German, French, Spanish, Traditional Chinese, Simplified Chinese and Italian and even a world clock. Just about the only thing this widget is missing is a kitchen sink, though I'm sure an eBay widget could help you even with that minor setback.
One complaint I have about this widget is the explanation as to why you should register it from Hawk Innovations. Discussions about whether one should charge money for a widget aside, check it out: "Our demo version has a 50-50 chance of working. Make sure your widget works 100% of the time by registering now!" Cryptic as that may be, I think it deserves at least a few points for being one of the more... unique demo limitations I've seen.
So, a '50-50 chance of working' demo is available, and a license (which includes two machines) will run a mere $5. Hey: nobody said making eBay's 'favorite customers' wall was free.
