I'd just go scratch start TIG and be happy.
Basic starter TIG rig, add more/different cups, gas lens collets, etc as you learn:
An argon regulator:
The ESAB Prest-O-Lite Flowmeter CGA580-Argon/CO2 hold up OK under student use and are around 65-75 bucks.
, argon hose (I'd buy by the foot and get the argon fittings that use screw clamps instead of crimp-ons), and (Airgas/Radnor since I buy from them, but you can get the same stuff by using their website to find these then buying equivalent elsewhere):
RAD64005478 Tig Torch Assy, 25 ft
RAD64005406 Power Block (connects TIG torch to argon hose, put a plastic soda bottle with the bottom cut off over the TIG cable end for a see-through cover)
RAD64001960 1/8" Thoriated tungsten
RAD64005413 1/8" TIG collet
RAD64005415 1/8" collet body
RAD64005422 #8 TIG cup
I'd buy (not lease) an argon bottle from whoever I was having fill it, and buy my TIG rig parts there unless they are a rip-off. Make friends with your local welding supply, they can help you greatly. If they aren't nice, buy online. I like Indiana Oxygen for online sales.
You'll have around 250-300 bucks in the rig and some consumables, which ain't bad. Couple bills for the cylinder, but you need that with any TIG welder.
If for some reason you turn down that welder deal, let me know!
