I would recommend Zararadio. I have used Zara on a Compact Evo (2Ghz Intel Celeron w/ 256 Megs of RAM with a SB Live! soundcard) 24x7x365 for 3 years, and have never had the slightest glitch. For free software, it is fantastic. Of course, I have had reboots due to power failures and the like, but never because of the software hanging. Get it, you will not be dissapointed.
