I can see getting a K7S5A if you REALLY want to reuse your PC133 memory yet someday want to scrap it for DDR memory, but otherwise, why would someone want a refurbed $60 motherboard for $35 when they could instead get a refurbed $120 motherboard for $35-40? It's entirely possible to run a K7S5A without problems, but even when they're new, you're taking more of a risk.
Also, have any of you tried to get support for PCChips et al motherboards? For years their own website wasn't fully functional 70+% of the time, couldn't even download the drivers/BIOS etc. I admit that PCChips quality is way better than it used to be, but still not anywhere near convinced that it rivals the other better-known name brands.
As for the Newegg refurbs, I've had good luck with them, my experience has been that it's more likely to get shipped the wrong part, than a dead part. When the wrong parts were shipped, they were typically better than the ordered part, so it seemed like an out-of-stock-mixup-substitution, just a bit unsettling that there was no chance to accept/refuse the substitution prior to shipment.
