Tucows is good for shopping around, and if you already know more or less what you want you can usually give it a test spin. I find the reviews at ZDnet.com very helpful, though often overly positive. They generally tell you what a program is supposed to do. Last time I went looking for a program (in my never-ending search for the best way to back up my system) I started by reading some reviews there, then I did a google search on those programs. I think I landed at Amazon and read some of the customer evaluations of software sold there. Didn't buy either program after that. Instead, I'll buy a hard drive and use the Win2000 Pro backup or try out Norton Ghost (recommended by one of our library IT guys).

Good luck removing the hum. If you are successful, I hope you'll report back on what worked. I "trace" these tech threads that look like they'll help me solve problems later.
