But touching on that...it is worth adding an extra £200 or so for various consumables ( add gas too ) for getting started.
Tungstens, a method of grinding them, filler rods, gas, good mask etc, cleaning products, whether wire brushes, stainless wire wool ( kitchen scourers ), acetone etc.
I did use regular torch cups at first, then a gas lens, and now most recently the FUPA stuff with clear cup. And I do think the FUPA is helping me, but that's another £50 or so.
So maybe better to start with that, rather than upgrading each time and wasting money
