I love my Tig Machine, although I find that as time goes by I use my Mig more (for Steel)-I was raised in a Town where I would ride my Bike down to the local Welder just to watch him, and was always intrigued by how Metal was bent and Welded-he used Lincoln exclusively, and, I believe that is why I like Lincoln (although they make good machines to boot )-

I have Pro Tig 185 Lincoln, and I have outfitted it with finger control and a Gas Lens-I find the Gas lens offers better visibility and Gas control, so I use it whenever I can-couple that with Pulse control (a big deal to me, as I don't have to roll the controls to get the desired results)-with Pulse Control I can make Welds that look like the proverbial stack of Dimes-(although, with practice I can do it without it, but it's a lot easier)-

I think Miller makes a fine machine, and it's a shame you don't have a few of them to try side-by-side(some Welding Shops will let you test drive them)-

I have often thought if I should have gone with a bigger machine, but for me, a hobbiest, I don't think so-it just my opinion (your Mileage may vary ), but I think the Machines in this Amp range offer better low Amp control (in the 25-80 range)than others (which may give you better control on that 22 Gauge Stainless)-

For me it also depends on where/when I can get consumables and Service-
