"the Phonic is very easy to use and i quickly learned how to use it and plug it into my laptop to allow a larger screen."
Forgive me Mike for using your "system" thread for this post.
Respectfully "The Phonic" is a bit of a toy, it is the Radio Shack SPL meter of RTA's and 1/3rd octave resolution is not really enough to tune your system, that will leave you with a very general smoothed looking curve that definitely gives you a sense of what your hearing but not enough information to analyze or discover anything but the grossest problems.
For anyone in your situation, where you'll have a laptop around the the True Audio RTA(http://www.trueaudio.com/index.htm) for $39 to $99 is a much better tool and much more economical. You will still need a mic and a mic preamp (approx. $200?) should you not have these items already.
I just posted this as an FYI for those in your situation, in your case Mike if you bought the Mic Pre and Calibrated Mic from Rives to use with your ETF, you would have all the tools a non-professional would ever need to setup your system and evaluate its performance in room and the ability to print out and save results.
Hope that was helpful
