Default Looking for DIY audio cable tester

I've started helping a local band with their sound system and running into a few technical problems with running dozens of cables. Does anyone know if there's a circuit for a DIY audio cable tester? I've seen some simple continuity testers, but I want to be able to check balanced XLR cables for shorts and phase reversal too. Looking for a simple but innovative design with a few LEDs which doesn't require switches and fancy circuitry. Thanks.

i'm partial to the Whirlwind Q box, the fact that if you have two units they can be used as a mini comm system is valuable. Qbox - Catalog - Whirlwind

but after looking at Jon's suggestion i might have to put that SoundLab unit on my Christmas list!

Google "audio cable tester", and you will see zillions. The $16 one at Guitar Center ought to do fine, but there are a variety on the $30 range. I really couldn't build one for that, and unless you really wanted a project rather than a useful tool, I'd go with the commercial unit. I had a little WHirlwind one I used for years and years, but more recent ones will include Speakons and others, which you will want. These commercial units all will allow you to flex the cables to check for intermits.
