One thing about regulators is that they do go bad - depending where and how you store them etc. When they do go bad, a quality brand like Victor is easily rebuildable.

That being said, Victor regulators command a premium.

For TIG welding, this is what I have: Its a Smith, decent quality and about 1/2-2/3 of the victor equivalent:

The second output is for purging/backpurging when working on stainless.

You could instead buy two singles (and two bottles). Saw this price:

As for flowmeter vs. flowgauge. Both could work. However, understand that a flow gauge is really just a calibrated pressure gauge. It measures pressure drop accros a known size oriface. It -assumes- there is little or no pressure on the outlet side. On the plus side, you can set it up without having the gas actually flowing. Keep notes on what settings work with what cups.

Flowmeters aren't perfect either, but keep in mind this isn't brain surgery. There is a broad range of gas flows that will work. In this case, good enough is in fact good.
