Currently have (3) ECS ks75a boards.
1 with a 2200XP 512DDR G4 Ti200 OCed to 500 specs
1 with a 1400TB 512PC133 G3 TI200 (oced)
1 with a 1000Duron 128PC133 Matrox M2 (arcade Cab)
Havent had a problem with any (in fact my Cab has 42 days
uptime currently) this board is a great board (IMHO) for the price, and since it is the #1 sold AMD board out (cant remeber where I read that) , there is alot of info on it (check this out)

It wont perform like a $200 board (or in fact some of the $100 newer boards) but being able to use older RAM or Newer is a big Plus in my book if you ever upgrade again.
If you look at a few reviews it holds up well side by side with much more costly boards (IMHO 2-10% slower then a board that costs 2X as much isnt bad). This is the board i put in all the quicky computers I build since i know its going to work, and work well.
Horror story: Bad stick of ram stuck in my brand new KS75A board, machine wouldnt boot up, smelled hot, couldnt find where heat was comming from, left machine on for 20 minutes, no fires, but wouldnt boot, swapped everything out that i could think of... bumped ram chip after about 2 hours of fumbling around, burned my hand, chip was actually melting. Pulled chip out, put new chip in, KS75A has had no problems yet (I burn DVD's with this so it has run for 5-10 hours straight many times).
I cant say enough good about this cheap board. Of COurse this is only my opinion... AND!!!! im talking about the older board not the newer one ( building another machine soon so will take a look at it soon).
