I use a Lincoln SP 135 Plus, but it's no longer a current model. It's been bullet proof and makes a fantastic weld. I have a friend that has the equivalent Miller, and I don't think you could really tell much apart from them in terms of quality of weld. The torches are both nice, but they are different between brands (at least to my feel), so it may make sense to put your hands on the torches and see what you prefer. I know I much prefer the feel of the Lincoln.
There are two things I'd recommend if you plan on working on car type jobs (1/4" plate or thinner material). First, the 120 volt is plenty of juice, and I've never had to turn mine up all the way even with slightly less amps than the new ones have (135 vs 140). A 120 volt welder is just more flexible if you have to go somewhere to use it away from the garage, and I have yet to run into a time that being 120 volts has hampered my efforts to get something done. On the other hand, 220 volts is great in the garage, but not so great behind the house at your shed or at your buddy's house who has no 220 available. Either get a dual voltage model or stick with 110 volts for your first welder.
Lastly, spend the extra and get a model with continuous voltage adjustment. That's the difference between a good 110 volt welder and a bad one. There are many times where adjusting my voltage down by 1/3 of a step between letter marks on the dial cleans up the weld significantly and the pool is just right. If you get a voltage dial with steps, you'll find yourself wondering why the welds aren't quite as clean as your buddy who does have continuous voltage adjustment.
In addition to my Lincoln MIG, I also have an AlphaTIG 200 (2015 version) which has been stellar. I mention this because I believe they are selling AlphaTIG through Home Depot online. While I use my MIG for welding parts together (such as installing a floor pan, etc), I use the TIG for repairing panels and filling voids in panels. It's much more precise than a MIG and you have exponentially more control over puddle, which allows you to actually build metal into holes without burning through the existing metal. TIG is a little slow for tack (or spot as it's often incorrectly called) welding panels together.
Due to my recent experience with the AlphaTIG, which has been very positive with a good deal of use (been through a few bottles of Argon), I would not rule out their MIG welder either. They make a nice looking little 110v that I believe has continuous voltage adjustment and otherwise seems to be as well made as their TIG. It would be a good deal if it holds up, but I know that I like my Lincoln enough that I may still rather pay double for it. If I were on a budget, I would probably be very willing to give the Alpha MIG a chance over a Lincoln, Hobart or Miller without continuous voltage. I just feel that step voltage is a deal breaker for any MIG and highly recommend staying away from a step voltage model from any brand.
Good luck!
