Mine have thermostats just like a furnace. They DO NOT heat quickly - this is a very slow heat and not to be used like an off and on switch. We turn them on for the "winter months" and then turn them off.
I think that would be an expensive solution for a "shop".

Yup! Especially since the OP is in Minnesota.
A friend of mine is from Minnesota, he walks outside without coats at 20F. Ohio, is relative warm to up there. Anyway, The Radiant Tube heater is the best option, it has thermostat. The tube heater can be designed by one tube, U-tube. We work in the garage at temperature of around 55 to 60. Jack can heat it up to paint to 80F, and it is like the sun. Traditional gas furnaces sort of suffocate you, because it is heating the volume in the room. The garage floor is relative warm, and the cost is low.
My parents home that was built in 1962 has radiant heating in the floor. Not all the floor is actually warm, and it takes hours to heat up the system. It is gas fired boiler, but you still need electricity for the pilot light.
If I was building a garage, and could afford radiant heat in the floors, then I would have it installed.
A retrofit system can be costly to install. You can contact your local plumbing/heating contractor and they can give you estimate. I recently looked at both options, but I will do radiant tube heat in the ceiling.
