There's one more choice no one has talked about - the Shuttle AK32. Uses the VIA KT266 chipset, has 2 slots for SDRAM, 2 slots for DDRAM, and onboard audio. I have one in my system - used my old SDRAM for about two weeks until I sold it to get DDRAM, so I can honestly say it works great with both. The AK32 runs about $67.
