OP,
No experience with the Origin arm, but if SOTA's bundling it then I'd trust that they justifiably consider it a good match and value with their tables. I called up SOTA years ago asking about an armboard for a VPI 10.5 arm (dealer wanted trade me one), and they said in no uncertain terms "NOT recommended". I never liked the feel of wobbly VPI unipivots anyways. My vintage FR arm has been a brilliant match. I think you want rigid gimbal bearings on a suspended table, though the heavily damped and stabilized Graham Phantom unipivots should do well too.
I'm a "set-it and forget-it" guy when it comes to VTA. I find a setting that sounds best for most records, and leave it there. I even have a Graham Phantom Supreme on my ClearAudio deck, with easy on-the-fly VTA, and never touch it once it's been set for a cartridge.
I really like the ClearAudio decks too. They do get spendy. I bought my Innovation Master, used trade-in, on large discount from a dealer. The Marantz rebadged CA mentioned above is from their older line. I've seen some pretty mixed reviews on that one. Their current lineup is simply outstanding; I've played with many of them. I'd only advise you stay away from the fully magnetic bearing Clarify arm. It's a mess. Don't go fully magnetic on arm bearings. The hybrid rigid/magnetic Magnify arm is outstanding.
