Victor and Harris both make good stuff. Sometimes it is easier to find
Victor tips than Harris. But if you buy the "Victor compatible" Harris
stuff, that is not a problem. Mostly comes down to what feels good in your
hand and what is the best deal.

As you can see, refilling small bottles costs almost as much as larger ones.
That is because most of the cost is in the labor, which the pretty much the
same either way.

Victor and Harris both make different grades of regulators. Equivalent
grades seem pretty much the same to me.

Harris does offer some things that Victor doesn't, like injector type
mixers. They make it simpler to use alternative gases, like propylene, for
cutting.

The prices you quoted for either the Harris kit or the Victor kit are more
than I would be happy paying. Check around on the internet and eBay to see
what they go for.

If you like Victor and are put off by the price, check out the Firepower
line, manufactured by Victor in the U.S.A. But stay away from Harris and
Victor knockoffs from offshore.
