Still have all my Plasmatics vinyl. Easily in my top 10 best punk bands ever. Never duplicated.
Honestly, you are correct! For me, Wendy set the standard for me once I discovered her and the band. Ironically I discovered them from the original Hells Bells the Evils of Rock n Roll when the Metal Priestess ep was being discussed. Granted this film is from a Christian point of view and being an open minded person I try to be I though why not give it a watch and discovered that the guy who made it seemed to be more open mined then the usual evangelical. To me he seems to be the type of person that I could have an open debate on basically anything and not get into any kind of a heated argument by the end of it. Shit now that I think about it I just might find out how to contact this guys ministry and email them, which a quick google search should produce the needed info, and actually attempt an open debate. Look this film up, which is where I stumbled upon it and was still there, at least the last time I checked, and give me one good reason.
And as far your original vinyl is concerned, I would get them appraised, if not already, because given the fact that the band isn't together any more and the fact that Williams committed suicide, these peace's of rock history my actually be worth some decent bank, of course depending on the over all condition, whether or not there autographed and I'm assuming that they are not in the original plastic or at least the packaging has already been breached which would, in my mind and I'm not in the appraisal business to be clear, would bring the value down as oppose to an ideal situation being mint condition, i.e. left as they where when purchased without so much as a crack, dent, ect. in which case it comes down to whether or not they are autographed. But I am also assuming that you would have to be a serious collector with a decent amount of cash flow to even begin to buy these type of items, if in fact that they can be found.
