The Guru of 3D posted a review on the ECS X58B-A motherboard

Guru3D Motherboard test - ECS released a drop-dead gorgeous looking X58 motherboard. It's feature rich has a few hidden Easter eggs and get this .. it's less than 249 USD. Now this motherboard is a BlackEdition. Meaning black PCB, a solid color schema connector wise, extra hidden features like micro switches for power/reset and even CMOS CLEAR, optical audio TOSLINK outputs, copper heatpipe passive cooling, dual GigE Ethernet and heck it's even SLI certified for two way SLI.

Now it might not be able to compete with 350-400 USD counterparts feature wise .. but it's certainly able to be just as fast and very likely the most affordable X58 motherboard you'll find on the market today.
