Iíll give you the different answer.

I have a pro tig 205 from harbor freight. I love it. Digital controls, pulse, ac/dc. I got an open box deal out the door for $600. Iím positive it isnít as good as the big guys. Iím positive that it will break down at some point and letís wonít be available. (3 yr warranty). But for me, it has performed flawlessly and well beyond my abilities.

Very happy with mine and the price/quality/value mix is good for a hobbyist. A very capable machine with all of the modern features, including a quality pedal. Even comes with a CK torch.

Don't you anyway need a gas welder to relieve heat stress after TIG/MIG welding?

Short answer, no.

From my research, 4130 under .125" thick does not need to be annealed after welding to produce quality results. Pre-heating will help a bit and general guidance is not to weld on any metal that starts out below room temp.

The little inverter machines are great especially on aluminum but don't have the duty cycle specs of larger machines. Which is probably not much of a problem for the hobbyist. I have an older Syncrowave 350 with chiller that I bought for much less than the price of a small machine.

I picked up a Miller Diversion 180 from the Miller booth at Osh a few years back at a significant discount. It is really simple to operate, does 4130, stainless, and aluminum, and performs flawlessly. It took a lot of practice to get decent welds (slow learner, apparently) but I find the quality of the welds is really great. It is hard to tell that a knucklehead did them...

I have done a full 4 seat Bearhawk fuselage with it (trust me, that is a LOT of welding....)

I have done a lot of welding but tig only in the past 10 years but I don't think I could have passed a tig certification test even before my cancer. Lots of things come into play later in life that aren't good but mainly steady hands and vision. Use the best helmet you can afford. I don't know what gave me cancer but all the gasses I breathed wasn't good. You need good ventilation but can't let it destroy the covering gas. Right now, I think a rivet gun builds a great airplane. You can drill out bad rivets but welding something again is difficult.
