[AT] Welders

[Mike M]

Hi all,
I'm in the market for a welder and would be interested in getting opinions as to what type to get. It would get used for machinery repair (tractor, brush hog etc). I was looking at some of the MIG welders at TSC the other day, and they looked nice, but were pricey if they are able to weld thicker steel. I've never used a MIG welder, but have used an arc welder in the past. An arc welder seems like a simpler choice, but I would be interested in other opinions. 
Thanks,
Mike M
