MSi K7T Master
6PCI, 4DIMM, 4X AGPPro, onboard FireWire and SCSI160
If not try the MSi K7T Pro, one less DIMM, no FW and SCSI.
I've used a Gigabyte board before and I had absolutely no complaints, I haven't seen much about their Athlon boards, but I like their boards in general. Especially if that board has Dual BIOS, that's a cool feature to have.
I'd check out MSi though, they make some really nice mobos, they don't have the overclocking facilites of an ABit or an Asus (no multiplier adjustments I mean), but I don't care about that, and you said you don't either.

Edit: They also make a damn fine i815e (The 815E Pro

) if you are looking for a good intel board.
If you're interested in reliablity of MSi, Anandtech's webservers all run on MSi K7TPros and Thunderbirds

If it's good enough for Anand, it's good enough for me.
