Welding noob, hows this one or other suggestions

The 220 volt 180 amp range welders are a very good choice. Lincoln is one of the reputable brands as well. One thing to look for though is to make sure you have both continously variable amperage and wire speed. The units I've seen at the box stores just have click settings instead of infinitely variable. On the thicker material the click settings ar OK but when you get down to sheet metal it is very nice (almost a necessity) to have the ability to make changes in very small increments.
