not sure if this would be of intrest but I recently purchased a handy little tool by Phonics called the PAA3... personal audio assistant 3. Its a $400 handheld 31 band SA, rta, rt60, with eq adjustment feature, with built in noise generator, spl meter, with usb, xlr in/ out, built in mic, and more. also includes test disc and computer software. small, handheld, backlit, battery powered unit is very fun and informative...for me anyway.
