Look out for a Century/ Lincoln--run fast
If you plan to build several, it is addicting, look for Hobart or Miller. Both have mig welders for running on 110v
Stay away from a H.F welder as well, even if you convert to a DC output mig. Did the conversion to a Century/Lincoln mig and the transformer took a dump after about a year.
Buy quality once or buy second rate several times.
