Well, I definitely want gas. Thankfully, I don't have to rewire: I have a 60 amp service to the garage, and it's already wired for 220. While 220V is an option, I haven't seen any compelling reason to step up from a (good) 120V unit for what I do. I really will be limited to bodywork, exhaust and maybe motor mount type stuff. I wouldn't turn down a cheap (good) 220V unit, but they're harder to find in this price range.

I know that you're from the GTA as well so I'll warn you with what I was told, that the Lincolns that Canadian Tire and such sell, are not quality units. They have a pro and consumer line. Ironically, if you go on Lincoln's site, they're priced exactly the same.
A word of caution if you hope to just use the welder without doing any wiring changes. While they're 110v, they require a 20 amp circuit. Odds are that your garage circuit is already overloaded and is not 20 amp, so you'll have to wire a new outlet anyway. So if that's holding you back from a 220, then it's really a wash... you have to rewire anyway, the 220 will cost you more upfront but you'll have more flexibility with material thickness.
