Gregory's ServerPerfect! I'll think about getting an ST300 ordered today.
I saw they have the ST400 but for the purposes of a dummy boot drive from ISO; encryption is way overkill. The ST300 lists that it supports exFAT too, so I don't have to resort to NTFS.
And yeah, I read the original thread; ever since I discovered that application I've been leery of it; (just skeezy vibes from the website and project as a whole, but it was the only utility I was able to find which allowed me to boot ISO images without a pocket full of USB sticks).
