mig is alot easier to learn and get into tight spots etc but theres not a damn thing wrong with a good stick welder especially if thats what you have. If a wire feed is on your wish list then definately buy that over a stick, alot more flexible and versital for the kind of stuff we do on our trucks.
not being a richard or anything (shaddup Chris
) but do you have any welding experience? if not then let someone who does do your welding untill you feel comfartable with the quality of your welds.
