I bought an MFJ 259B analyzer about 6 months ago, and I don't know how I lived without one. They sure do make setting up your antenna way easier as well as letting you know exactly what is going on with all the parameters.
The one thing I do wish I had done was to spend a little more money and got the next model up for the UHF band.
There are other brands out there that do an excellent job also, Just be sure to read up on each model you are looking at to be sure it will do all that you want in an analyzer.
If you build you own antennas, they are almost a must have, worth every cent spent.
The ARRL has a book on using antenna analyzers that is decent. It gives enough info to help one understand how to really use one to it's best use and compares different models and brands, so although not their best book, it too is worth buying if analyzers are new to you as mine was to me.
