Magnum dynalab

I'm looking for a good place to purchase Magnum dynalab products. Anyone with experience to make some suggestions?
If your looking for a tuner then check here on Agon. Look most people on this board are very anal when it comes to their equipment. At the very least something on here may have to be cleaned inside but the money you would save buying used is considerable enough to have a tech clean the inside of whatever you buy and to make bias adjustments and still walk away with a couple of hundred saved.
