Asus A7M266 is a very good motherboard.  FIC AD11 is a good motherboard with multiplier settings.  I have a MSI K7 Master due next week and from all reports this is a very good motherboard.  Epox has just released their 760 board which looks to be a very good board spec wise. Along with boards from Gigabyte, Aopen, DFI, and Biostar all of the above boards are based on the AMD 760 chipset.
You have several choices from Soyo, Iwill, Asus, and others for ALI based DDR boards.  The performance of these boards are good and stability has proven to be very good.
The VIA KT266 DDR chipset is going through growing pains currently but all board suppliers will eventually be offering products based on this chipset.
