I have a good local friend who’s a smart, cautious guy. He’s owned a Scoutmaster for some years now. He’s very thoroughly explored the Scoutmaster-to-Prime option, and conclusively settled on sticking with the Scoutmaster. From what I understand of his findings - the S.M. is a solid table, and there’s no reason to execute a potentially lateral move to the Prime. I think if his findings were at all in favor of the Prime, he’s have done it. But he did upgrade to the 3D arm, and likes it. Seems to be a good arm for MC carts - but I told him to consider the Gimbal fatboy if he wants to run Koetsu in the future (they need good rigid bearings).
When it’s time for the REAL upgrade a few years from now, he’ll certainly be exploring other brands too (e.g. Brinkmann).
