BIOS Man would save $5 to $10 over Bad Flash. They offer a subscription for your PLCC chip, and will sell you a chip-puller for an extra $10.
I can see you have a mobo that is at least 3 years old, and I understand your "financial trade-offs" and preferences. Per my new hardware, though, I'm beginning to consider using BIOSMan on a regular basis, after just recently having a "flash" disaster for the first time in 13 years and maybe 20 computers with as many as 60+ successful, uneventful flashes.
