Yeah, but I've heard about as much, but do know at least one fellow who says good things about them, though some of my Internet readings would disagree. There is a MicroCenter near me; once in a while they do have killer deals on CPUs, mobos, etc (I can't forget that I got a super vid card there, the ATI Radeon 9700 Pro 128 Mb for less than $170, over two years ago!). But I kind of avoided the Soyo ones. I am also leery of Biostar, and Abit, now that they were snagged using inferior or defective components on what was sold as one of their leading boards. I think I pay a slight premium for the MSI or DFI brands, but they have a fairly sterling rep backed in my eyes by my own experiences. I don't like extra trouble down the line once it's built, kinda like not wanting to get up once my shoes are off and my heiney is on the couch (all right, to tell the truth, once my heiney is on my chair in front of my PC).
But if this rig for my younger one goes crosseyed because of RAM sticks from different manufacturers, I may have no choice but to make a matched set; i.e., get rid of one (boo hoo) and match the remaining one. But I've heard that these days, most of the "name brand" makers make RAM technically so good that there *should* be no mismatch problem.
In case any of these outfits have reps here, this is, of course, my "private" opinion.
