Today I converted all my eBay "favorite searches" over to RSS feeds that I can now track in my RSS reader. I think eBay started the RSS stuff this week, I think this rocks. Now instead of getting an e-mail alert per day, I can set the polling rate to 1 hour and see any new auctions within the hour for my favorite searches. I usually search for any empeg related stuff, and am currently in the market for a rear cargo cover for my car, so I just set up those searches and away I go.
Also, you can get RSS feeds from the Empeg Wiki special pages. Anytime a new article is written or one modified, I get alerted through the RSS reader. Any other cool RSS type feeds that you've found that are especially useful?
