My neighbor, W6GJB, has a Samlex unit that he says he doesn't hear on his antennas, but "doesn't hear" depends on how far antennas are from the noise source and what your background noise is.

Samlex makes several models in several series. The "quieter" ones are those that carry listing for UL and FCC Part 15 Class B. There are models rated for 300W, 600W, and 1kW. Model numbers are PST-300-12 (300W, 12VDC to 120VAC), PST-600-12, and PST-1000-12. They are all listed as "Pure Sine Wave" inverters, and the data sheet says "Low interference." Last I looked, I could buy the 300W unit for $148 and the 600W unit for $224. I don't remember where I priced them.

Don't interpret this as my recommendation -- I'm reading the data sheet and telling you W6GJB's experience. :)
