A bad stick weld will out last a bad mig weld any day. Probably will outlast a good mig weld too. Harder to learn for sure. 110v migs are not for welding major parts though. Sheetmetal and stuff, fine, but for frame welds you need the right tool for the job.

Best thing to  do is get the welder, some scrap steel and have at it till you feel good about it then go for the rig.
