yeh the more i read on the web it seems like I may opt for electric.

Only reason i didn't want to at first was i dont have 220 in my garage and if i have a heater plugged in to the wall i can't really use anythign else. So i think i might just put more outlets in and 220 and get an electric unit, but first before that insulate it because right now its so drafty in there no heat ever stays
