Very much agreed. If you've got the steady hand control to work with a stick's tip, WAY far away from your hand, then you'll have no trouble at all with a TIG torch electrode right at your fingertips, and you'll have plenty of hand support. Just get used to being VERY up close and personal with your work. There's no spatter, and its quite pleasant.
Just one thing. TIG is really fun and easy, -IF- you've got your machine and setup dialed in right. And there's the catch. With SMAW DC, you've got very few machine parameters (electrode selection, current, DIG, etc.), with the rest of the results coming from how you handle the stick.
With GTAW, you've got a whole bundle of parameters (shielding gas selection and flowrate, tungsten size, tungsten grind angle, cup size, gas lens or not, pre/postflow, current, filler size or no filler at all), which can really effect how the arc works for you.
Anyway, you've got the right group here, and you should have no troubles with this.
BTW, while I've never scratch started TIG myself, you'll have to without HF, and I've heard that it is much easier and neater, if you clamp on a small scrap of copper, to scratch start your arc off of, before hitting the workpiece.
