Garage heater brands

We switched over to a pellet stove last year. the fuel saved will pay for the stove this year so 2 year return on investment. but you want to heat the garage which would be quick bursts of heat while you work and none when you don't. propane turbo heater is what i would suggest will heat the place up quick. or one of the other electric or renzor heaters to do the same thing but with less emphasis on heating quickly.
also looks like a sweet jet engine when your running it
