I have a RigExpert AA-54 analyzer I am selling. It's about eight months old or thereabouts. This one is in perfect condition and has all the extra stuff that came with it plus I toss in a USB A-B with a ferrite filter on it.
Go here for a complete description of what all these handy dandy little units will do.

I'm selling this one to get one that goes higher in frequency. Originally, I didn't think I'd need the extra frequency capability, but after using it, I found that it could do many things my other test equipment won't do, plus it is a nice handheld size for portability and field use. All the readings can be stored and downloaded to a computer and further analyzed using the included programs on the CD.
They go for about $350 new. If you are interested, drop me a line, we'll talk.
