One the best for home shops is the CHEVALIER FCG-610 w/ airbearing. One man can break down and carry that grinder out to the trunk of the car and its vastly more useful imo than a single lip grinder. I think you need some sort of sliding table on a T&CG.
That is a lot of manual grinders to hit the market at once, I'd guess there'd be some low prices. They are a fantastic thing for us home shop guys, but in part made obsolete with index tooling....so it will be interesting to see of there is enough commerical interest to keep prices out of the basement. If you don't have a T&CG they are a really nice addition....and I see a few with motorized work heads (makes it a light duty cylindrical grinder) which is also a fantastic capability to have.
