I saw the UMIK mics from minidsp and imagine there must be a better solution for testing speakers. I do have a pro audio multi channel audio interface but would rather have a USB solution to make the test rig portable. What are some good options that can help me build a solid test rig for final tuning of cabs?
I think the easiest way to get useful info if you are starting from nothing would be the Omnimike. Dayton Audio Dayton Audio OmniMic V2 There are many other osolutions but all add complexity to getting something done.
I have behringer ECM8000 and Dayton EMM-6.
The EMM-6 comes with a calibration file for your mic. I got mine for around A$100.
The dayton mic and behringer deliver measurements within a dB or so of one another until 15-20k, at which point the differences still remain minor. In my mind this says that "yes, I could get a better mic", but these are doing just fine for my mderately critical measurements.

What is the ideal style of microphone I should look for? a simple accurate omni directional mic?
How does the dayton software rank with something like REW?

Look for a mic labeled 'calibration microphone'.
They are all small diameter omni directional mics.
Some reasonably priced brands:
Behringer
Dayton
Earthworks

Works nice with REW and has a calibration file.

the accuracy of the mics from dayton, behringer or minidsp seems low directly from the manufacturer, the accuracy should therefore be controlled against a known reference.
i think clio pocket system has the highest accuracy right out of the box

Checking mic accuracy is not a simple DIY project. It requires sending the mic to a skilled cal lab.
Can you post a link to the Clio pocket system you are talking about? Would a omni-directional ribbon mic work the best for this task with a pro audio ADDA? I am figuring they would be the most detailed and sensitive mics in general and able to get solid results. A pretty good one can be had for around $1,000.
The best microphone for measurements are the ones designed and characterized for that service like GRAS, B&K & Microtech Gefell. Ribbon mikes are intrinsically bidirectional and need acoustic stuff to become omni. This always brings compromises. There are other issues with frequency response and the transformers needed. A less expensive option are the Earthworks measurement mikes Earthworks High Definition Microphones . Still not cheap but directly compatible with typical pro equipment.
