For your budget, you can get the top-of-the-line
Taig/Microproto DSLS 3000, which is a turnkey system (you just have to provide a suitable computer). There is an advantage to getting a system built by one company, as this is (Microproto is the CNC arm of Taig tools) instead of pieced together from various manufacturers, since you'll get knowledgable support with no passing of the buck. The nice thing about the DSLS 3000 is that it monitors position and shuts down if it gets more than a tiny bit off. This can save a part that you've got many hours of work into. The Gecko 540 is a nice controller, especially for the price, but it doesn't do that. If your achieved position is different from the commanded position, an open-loop stepper controller like that will never know, and keep merrily chugging along, even though it's wrong.

Taig does offer a rotary 4th axis
and it's turnkey as well (and even comes with a tailstock), although adding that pushes it a little over your $3k budget. Here's a picture on the MicroProto site:
Rotary Table
While it's true that the system shouldn't lose steps if everything's dialed in correctly and nothing bad happens, there are times when I've been glad of it, like when a cutter slipped out and started cutting much too deeply, and when I was cutting a wooden part and hit a knot. The DSLS system also goes about twice as fast as the standard one, which is useful when dealing with softer materials, like plastic or wood.

Re: The right taig for ME?
I am a birt barcode developer.I'm interested to buy a new 4 or 5 axis Taig setup, and from my understanding Taig only sells the 3 axis mill setup. If price is not an issue, who or what small company sells the best 4 axis setup or conversion who has the best support, too....? Is there a clear frontrunner?
Re: The right taig for ME?
Taig makes a 4 axis mill; we sell the whole setup. They use a rotary table made by Sherline Tools, based in California, and they fit it with a base that mounts on their mill bed and an adjustable tailstock they make themselves. If you want 5 axes, though, you'll have to use something else. If price isn't an issue there are others to choose from, but if you are concerned about cost-effectiveness the Taig and Sherline tools are hard to beat in their size categories. Their support is top-notch as well, but if you use 3rd party controls and other equipment with their frames, they can't be expected to support all that.
