In another post there is some apparently tongue-in-cheek talk about "plasma refill kits". I've never heard of such a thing, even as a joke.

My first question is, are there some nutjobs out there who are actually trying to sell plasma refill kits?

And second, if I remember correctly, the earlier models of plasma sets were supposedly prone to leaking (or so I heard). Was the leaking plasma always a myth or was this a problem which was corrected along the way as the technology improved?
