A-80, EPIC ICE, and one of the ISIS prototypes have been my unicorns for years.
Insight Component Engineering is still in business. You can order new Epic Classics and Epic DV8s (upgraded trapdoor system) from their website. You can also find them in the BST here and on MCB for $200-$350.
Assault 80s obviously aren't available new anymore, but they can be found on Ebay for $75-$150, occasionally new in box. There were a lot of them made, and a lot of them didn't sell or made their way into closets/attics. If you peek through the BST on MCB and occasionally the "Technical-Paintball-Site-that-Shall-not-be-Named-on-PBN" (childish, isn't it?) you can find them for cheap.
As for the ISIS, well, that's vaporware-extreme. The one I held wasn't even an ISIS, it was a prototype made for some sort of sneaky fly-by-night transaction that went down right before Powerlyte went under. You'd have an easier time getting your hands on an eVolt or a BE-90... Even an original rotary-breech E-Phantom would be more feasible.
