I bought a MFJ-16010ST Antenna Tuner at a swap meet. The "ST" stands for "Super Tuner". But it turns out it was an odd production piece and was not offered by MFJ for very long. Initially it was very hard to dig up a manual, but I managed to find one.
Anyway, when I tried to use it, it didn't respond the way I expected. I couldn't match anything. When I initially opened it up, everything looked fine. But I finally took it completely apart and found a unsoldered wire that connected the toroid coil to one of the tuning capacitors. I soldered it on it's post, put it back together, and ran some tests. It worked like it should. I figure that's the reason it was for sale in the first place. I still use it now and then.

In my area, it seems that every pickup truck or SUV comes with one or more dogs. It's so common that I can only assume that the dog(s) must come with the vehicle. So logic tells me that, if you want to keep the truck for a long time, go for the multi-dog option. Otherwise, if the dog dies, you have to buy a new truck. I have five dogs (4 dogs as of 4/4/2013, RIP Katie), so I'm set for a few years.
