Since Anandtech selected it as an editor's choice, I would probably look at the
AOpen "AK86-L"
It uses the K8T800 and only costs $92
It does not have firewire or IDE RAID, so factor that into your analysis
An nFroce3 250 chipset motherboard that is available is the
GIGABYTE "GA-K8NS PRO"
It rings up at like $135
This is a more full featured board with IDE RAID and firewire, but I have not really seen it reviewed yet, so I don't know if it's any good.
Hope that helps.
By the way, prices are at Newegg.com
