And the cheapest of all the ones tested, as I recall. I bought it because of the price and the small size and weight. When I go on a trip I can throw it in a suitcase with the K3 and still have room left over for clothes. The only complaint I have heard about the MFJ-4125 is the fan noise. While it is definitely audible, I personally don't find it objectionable. For those who do, placing the unit under the operating table should solve the problem.
