I've used so many low-cost boards before (Asrock, ECS, Jetway and Biostar) so far the ECS boards are still working (K7AMA, K7VTA2), the Biostar boards died due to popped capacitors, the Asrock ones - well, all three suffered from the same defect - no power (K7VM3). The Jetway for socket 478 suffered from popped capacitors also.
Yes, its a poor performer than same chipset motherboards from other manufacturers, but so far they are very reliable, considering they are cheap.
