That's it, the only Sis 735 board is ECS K7S5A. It's a great board, dirt cheap, high performing, there is one bug related to Floppy Drives on Win2k, but that has been fixed by a new BIOS (go to OCWorkbench.com for this new BIOS). The only thorn in it is no ocing options, but I don't think that matters to you right? And I wouldn't expect many more SiS 735 boards to come with VIA playing the "Chipset Game" that Intel has done in the past to Mobo makers
