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 !!!
I've used 0.025", 0.030" and 0.035" wire in my cheapie machine just fine....With the rollers it came with. I'm not following the need for changing the liner out for different size wire, but that hasn't slowed me down either.
The tips? Yep, those are off the shelf too. Home Depot, Lowes, Tractor Supply, welding store, you name it, nothing exotic or hard to find. They work perfectly on my cheap China machine. You can even see some packs straight from Lowe's sitting in the cart.
