The best S754 mobo below $90 is the Soltek K8AN2E-GR nForce3 250Gb. $85 at NewEgg. Secondarily, the Biostar KHNA Grand is also very good, and in the $70 range. Another very good pick, and the least expensive of all, but does not come with as many bells and whistles, is the EPoX 8KDA3I and J series, the I version is $64.50 at NewEgg, but lacks the Gb chipset and uses only the nForce3 250. Beware on the EPoX mobos that they are following AMD's recommendations to the letter and if you use more than two one double-sided DIMM you will have memory running at 333Mhz instead of 400Mhz. If you plan to use only 512Mb, this poses no problems on the EPoX mobos.
