I think the Lincoln is really "entry level" - a toy almost! If you plan to do much in the future you'd quickly want an upgrade. The Miller is a nice little welder for a 110v unit.

The thing about name brands is the availability of parts. If you change wire sizes you ideally need to change the feed rollers, liner and contact tip. For name brands, these are "off the shelf" items at welding supply shops or on line. Just try to find a feed roller for a no-name welder or a liner !!!
