Er, "Go get", not "Got get"... (Need... more... sleep...)
I'm rather partial to nForce2 boards, though they ain't cheap
(relatively speaking -- my Tyan MP boards cost way more =). I love my
Chaintech 7NIF2, no problems to speak of, and its not a VIA chipset!
Though I never had any issues with my old KM266 board (MSI KM2M
Combo-L) with dual ivtv tuner cards either, and my current secondary
system is rock-solid (MSI KM4M-L, one very sparsely used M179). I think
I paid about $100 for the 7NIF2, and about $60 for the KM4M (both from
local shops). The nForce2 board does have the distinct advantage of NOT
using a VIA chipset, so you can be pretty certain it won't have those
DMA issues (both my VIA boards are fine, but YMMV). On the cheap and
non-VIA, I've had good success with ECS K7S5A boards, which use a SiS
chipset and retail for like $30 now.
