I'm not too crazy about them myself. My first experience with them involved me being one of those "no-coder techs" in the Oakland store in 1991. When I was up in Portland a few years ago I was inquiring about some of the small portable MFJ antenna tuners and was pretty much dismissed when I asked if one of them had a balanced output. First, he didn't know what I was talking about. Then he told me I don't need that, everyone uses coax these days, then went on to say I can't have everything. Well, yes I can. MFJ makes antenna tuners with balanced line outputs. He told me to take a look at the MFJ website., at which point I told him I was really interested in buying an antenna tuner TODAY, I just couldn't remember the model number of the exact one I wanted, and there would be no coming back tomorrow because I would just order one on the internet. He comment: "We really don't make much on antenna tuners anyway." Well, that's not the point. The point is I would have purchased an antenna tuner if he would have taken the time to assist me. And I don't understand businesses that have that attitude regarding items with a low markup. Even it is a few dollars, it is still cash flow. But since the guy was probably making $8.00 an hour, he just didn't care.
I did order an SDR play from them. They were the only ones selling them at the time.
