I think he was an awesome in ring performer. His run in ECW as one half of the eliminators was excellent and he was great in WCW especially when he was feuding with Raven and Chris Jericho. I think the thing that let Saturn down was his lack of a gimmick when he came to the WWF (Which I think was the WWF's fault because as with other talented wrestlers they have had on their roster in the past, they did fuck all with him)
Perry Saturn was awesome. I've always liked him, in ECW, WCW and WWF. He was a good agile and strong wrestler, who like you said looked believable in the ring with anything he did. Also check out The Eliminators vs The Dudleys from ECW's Barely Legal PPV, I thought that was a pretty sweet match aswell.
Not very familiar with him but I absolutely love his submission move called The Ring of Saturn. Batista started using it before he quit under the name Batista Bite and I think it's an awesome and underrated submission hold that should be used more frequently by wrestlers.
Also, I'm glad to hear that he's recovering from whatever troubles he was dealing with in his life for the last few years.
