I'm wondering how popular the LC III was (or not)?

Reason, I don't encounter hardly any of them where I look. Even on ebay they seem scarce.

I figured, I want one of those since they fit neatly on the desk I use for my PC (and hence I can hook it up to my monitor with the adapter), and upgraded with an Apple IIe card I could mess around with old 8-bit software a bit.

Of course, the LC II or 1 would do they same job but of course the III has a tad more juice in it.

So, why are they so hard to encounter?
