Same here. Not 'come across' but I have an orig. I traded a Tripsichord LP for The Deep AND Skip Spence - Oar, years ago. Still one of the best trades I've ever made :)
I do know someone here in Stockholm who found an original of The Deep for under $10 though, but that must be 20 years ago. She wasn't willing to part with it (I offered maybe a LOT more than $10, 15 years ago) because she thought "the sleeve was funny" :confused:
I wouldn't be surprised if it ended up in the garbage or at some attic...
The Radioactive vinyl boot looks and sounds good and as far as I know it's the only reissue that has the orig mix. Those Cicadelic/Collectables "reissues" has "remixed" versions that sound like total crap. No sound fx, tinny demo sound etc
