A couple folks have mentioned that the Duron is the "best bang for the buck" going right now. The Duron does cost a little less than, and outperform the Celeron, however for a low cost system I'm not sure the Duron is best. First, it takes a more expensive socket A. MB. Then, a more expensive AMD approved case with extra fans and bigger power supply, fan/ heatsink. I think it would really depend on one's application for the system to determine which is "best". One can build a VERY inexpensive general purpose system using the celeron with the currently discussed all-in-one MBS, e.g., 810 chipset board, etc. On a higer end system, I haven't really compared, but the Celeron is easy to OC and heat doesn't appear to be as great a problem.
