Meh, companies do this sort of thing all the time. And coupled with the fact that the Explorer had the complexity of an eCCR with none of the benefits, it's not really surprising that a $6000 SCR that was nothing more than a short term gas extender, didn't sell well enough for Huish to continue the product line after the takeover. It doesn't have the legs of a PSCR, and it's priced well north of the KISS units, and its niche is just way too small to be profitable considering the cost of production.
There's nothing really wrong with the Prism, it's just another bog standard CCR. There's nothing really special about it. It doesn't really offer anything new and innovative that would make me want to purchase one over any of the other units on the market. It doesn't have the bombproof construction of a Meg, the streamlined profile of an SF2, the redundancy of a Revo, the mass market saturation of an Inspo, the automated function of a Poseidon. It's just sort of there. Doesn't mean it's bad, just isn't anything special.
As for trusting Hollis, it's now owned by Huish, so it's got capital to back it up. As far as trusting them, that's a personal choice. I wouldn't buy a Prism in the first place so it's not really a decision I would have to make.
