Currently have an Omega8000, which I love and have had lots of luck with. The one thing that bothers me a lot about it is that it is VERY sensitive to EMI. Almost anytime I get near a power line I get tons of interference, sometimes to the point of turning sensitivity down below 50% or even giving it up as a useless act of futility. Thinking about ponying up the money for an Etrac, but want to make sure that I wont have a problem with constant interference.
