Well, about the Baldor, they are intended for "industrial" use, and like you said, they will probably outlast both of us. I am 75. The housing under the grinder is intended for dust collection. While I do have and use the Wolverine set up, the only way to use it on a Baldor is to either cut off the bottom of that wheel housing, or like me, do all of my sharpening on a platform. I have looked at the Tradesman set up, and for sure, it is a sweet set up. They were originally intended for diamond wheels and sharpening the CNC bits which are carbide. Even a slow speed Baldor is too fast for diamond, and will overheat the diamond and cause them to break down way too fast. You could cut off the wheel housing enough to slip a Wolverine set up under the cut off, save the pieces so some one else can "fix" it after your birth certificate expires.... I have heard of some taking the Baldor grinders and angling the base, tipping it enough to get the Wolverine under the housing. Not sure how that actually works. Oh, if I had the chance to pick one up for $475, I wouldn't hesitate. You might ask them if they have any "factory reconditioned" ones for sale....
