I thought it may be of some help to people starting out to know what some of us are running for transmitters Hopefully we can get a little bit of a list going. The one I bought is by Hlly Electronics in China. So far it has been very reliable and has not missed a beat. Sound quality has been good. It does mono and stereo output. Quite cheap compared to other brands on the market http://www.hllyelectronics.com Please check relevant authorities on broadcast signal strength limits etc before choosing one.
