Personally I would go for an arc welder, with some practice it works well and you don't need to faf around with welding gas and there's much less to go wrong so tend to be more reliable. There also cheaper so you could probably get a high quality arc welder for the same price as a poor quality cheap Chinese mig welder.

But saying that MIG is so much easier so I can't understand your choice. I'm not so sure in brands though.
