I sold my first commercial fly well over 40 years ago and have gone through stages of tying hundreds of dozens on short notice... Sweat shops have eliminated the orders worth tying and only custom or special orders work financially, so I have not been tying commercially much lately... but I have, have had, or have used about every brand and every model of vise anyone can name. I still have a bunch of different vises including a couple Renzettis, Griffins, an HMH, my original Herter's vise, and several others. On this site I have sold or traded a number of vises including Griffin, Regal, and HMH. My new Nor-Vise just trumped the entire lot.

There is nothing the Nor-Vise cannot do better than any other vise, period.

While the price is not in the original poster's range I go this route because I look at all the time I have spent in front of vises and how much more I would have accomplished starting with the best vise first. I would not know what it is like to struggle with mediocre jaws; rotary techniques would be second nature and my speed would be vastly increased; ribs would be perfectly spaced, truly parallel, and laid down that way first time, every time due to the nature of fine tuning the wrap at exactly one point and only one point.

If you are truly going to get serious about tying flies a horizontal-bearing rotary is the minimum initial starting point. There are many vises I have bought that cost more than a Nor-Vise. Knowing me it is unlikely I would have bought just one Vise, even if I started with the Nor-Vise, but there would have been far fewer of them and they would not have been able to fool me into believing they were superior. The Nor-Vise IMHO will make any tyer better.

Buy good stuff and cry once or buy second-rate and cry often...
YMMV
