Greetings,
Have you tried McGrath-Rentelco? If you are going to be seeking Techs to operate that thing, let me know. I am just now trying to make a decision concerning the direction of travel I will be enjoying soon. I can send Resume' for your viewing, excellent references, and am open for meeting new people and seeing new lands!!! I have a couple other links for rental Test, Analysing, and Generating Signal equipment.
Take care, Petergunn.
