Well, there's tons of manufacturers out there...
The one I have is by Emerson / Control Techniques... It's a Commander CDLE. http://www.controltechniques.com/
But there are literally hundreds if not thousands of manufacturers... Everyone from Westinghouse, G.E., Mitsubishi, to weird 'no-name' brands.
Here's a good primer on their operation:

I don't really feel I'm in a position to offer advice on buying them, or which brand is better than another. All I can say is to a) get a decent reputable brand and b) if you can't tell from the manuals, call the company and make sure it isn't 'too smart' and can run on less than three phase input.
Like I said, mine is a Control Techniques 35HP Commander CDLE. It works flawlessly for phase conversion. But 90% of other ones out there would probably do just as good of a job as this one.
Check eBay for them, or surplus industrial supply houses... I got mine from a company that buys/sells surplus industrial manufacturing equipment.

Oh, and this is KINDA what mine looks like... Mine is slightly larger, and cleaner, but just as green... Lol...
This pic is just one I found online, not of my actual unit.

My favorite brand of VFD would be Dan Foss or ABB. They are both easy to use and must be pretty dependable because I see them everywhere in HVAC units.
If I had to chose, I'd probably go with Dan Foss since I have fresher memory of using those. (they had really easy to use override settings, as I recall)

Brad, Thanks for the tip. I have always wondered about doing that but never had the balls to try it.
I also wanted to try one of these for laser

They come very highly recommended in the CNC world.
