I have an IA 187 10. Never been powered. Still in factory box. $75. I also have a 4" aero port from Precision Port that I was going to use with it. $16. Depending on where you live, I could do both for about what you want to spend. All you would need to do is build the box. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
