Would have to agree with the Daiwas, and will throw in two more "used" choices: The Kenwood SW-200/2000 series and the Drake WH-7.

Judicious shopping will net you a unit which is in very good shape. The Kenwood setup has the advantage of using sampling heads - a maximum of three per unit. Thus, you can look at HF, VHF and UHF power sources at will by merely rotating the meter's input selector switch.
