It’s this heater: https://www.amazon.com/Honeywell-HHF360V-Degree-Surround-Charcoal/dp/B00VV156LA
I think I got it at menards or target. I did no research before I bought it and I’m not sure if I’d recommend it, but it does the job. My main point is just that having an insulated garage door that doesn’t leak air around every edge is every bit as important as getting a heater.

I made a low tech one by using this heater, this coffee table and a queen blanket I had lying around. For the coffee table use the board that goes underneath the table as your wood that goes on top. I eventually ended up cutting the legs down a bit to make it more comfortable to work on my laptop full time. just make sure you don’t cut it too low for the heater.
