behringer CT100 cable tester
You have to have a cable tester if your running any kind of studio. You can have the best gear in the world, and a $8 cable can ruin your day. Maybe just your take. Don't know how I managed so long with out one, but I did. I looked over the catologe, and the behringer had the jacks I use, mostly 1/4 phone, TRS, XLR, phono, MIDI, RCA, and TT. It looked simple to use, and it is. At the price, you might think the build quality might not be great, but you'd be wrong. All you have to do is remove one small phillips, install 2 AA batteries, and your good. These work well, and the price is right. Just one of those things you have to have. You can spend more, but I don't see why you would. I expect to get a lot of use of of this piece of gear for a long time.
