Craigslist Ad Alert recommendations?
 

I need ad alert software but I am always weary of shareware or anything I have to download. I have downloaded free stuff before and was never ever able to undo it.

Does anyone have recommendations as to what is good out there? I am willing to actually pay money to get it. I just need recommendations.

This is about the best looking I spotted and its google based :

Pick your favorite RSS reader and load up the raigslist RSS feeds that you want (do it by category). The CL RSS link is near the bottom right corner. My RSS reader sorts everything into folders that I set.
