If you have your heart set on a Kurt and don't mind spending the coin to get one then I say go for it. I've never owned or used one, but my understanding is they are awesome.
When someone asks me a question like that, I ask them what do they plan on doing with it? Are you a production shop or at least planing on doing a lot of work as a business? If just a hobbyist, then do you have a huge budget for your hobby and have plenty of money for not only a vise but all the other tooling, cutters, collets, holders, measuring tools, dividing heads, turn table, angle plates, etc. etc. that you will need to get tooled up? I think you can see where I'm going with this...
I have two mills. One has a 5" and one a 6" mill vises. Both are imports and cost me much less that a single Kurt (bought one new, one used).
If your budget is limited, pick your battles carefully! If you currently have no tooling, you've got a long row to hoe!
