I currently have a Miller digital elite and a Lincoln Viking 3350. Both are excellent, the my Viking has a larger viewing screen which is helpful sometimes but it weighs a lot more than the Miller (hurts the neck after a while). I used the Viking for the last 6 or so years with great luck, only changing consumables. The Miller I've had about two years, also just consumables. Can't go wrong with either. I do a lot of low amp Tig on stainless and aluminum and both have plenty of adjustment. I do less mig these days so replacement lense covers aren't a big deal for me anymore, but if mig is your primary I would compare the prices of replacement lense covers before you buy. Both companies will often sell odd color combos on sale for a great deal.
