What model Mig

[Roger M]

I would go along with everyone that recommends the miller 175( or whatever the current model is). I dont have a welder yet, but that is the welder I plan on buying when the funds are available. Vince (aka MR Quick) has a good idea about where to get a good deal on one. The only drawback to buying online is that you wont have as good of support/customer service as you would if you bought locally, if something went wrong.
My garage didnt have a 220v outlet either, so i asked an electrician that i met on a job about how to put one in. It was pretty simple as long as you can get wire ran from your breaker box to the garage. You should also make sure that your circuit panel can support the extra power demand. I did it myself and I am not eletrical genius. I needed that power to run my compressor.
I would bet that some of the electricians that frequent this site can chime in and give you some advice. I do not recommend atemping this project with some good guidance first. Electricity is not something to take lightly. Good luck.
