I had a horizontal flow natural gas furnace (80,000 BTU) in my old garage and while it kept the space warm(+10 C or so), the floor was always so cold you could see your breath when you had to work under the car and your feet were always cold. 
Electric is OK, but you really don't get a lot of heat out of a 110 volt outlet. BV’s is available from Lee Valley Tools, which looks to be a good unit. I think regular outlets are rated for only 1500 watts of power, so if you plug in your heater and then a power tool or something, you end up popping breakers. Plus, electricity is much more $$ per BTU than gas  is (or used to be, I haven't priced it out lately though)
Of course, we are talking Canadian Climate, so your needs may vary depending how cold it gets where you live.

Now you tell me! After I've already poured my pad!
Well, I was at Costco, and they have those focused beam electric heaters. It was $60 so I got one. I'll try it out, see if it does the trick. What is nice is you can actually aim it to where you're working, and it heats the air everywhere too on thermostat.
I really like the looks of those electric ones you guys have pointed out, might be a way to go, but the cost of electricity may be an issue. I've been thinking of running natural gas that way, it may be the way to go for the long run. Anyone have some suggestions for natural gas heater style/type/brand?
