I don't want to belabor the point. But I am finding RampMeters run in the $100-$130 range. That doesn't seem excessive when a DCC/Sound locomotive costs $250-$400. It is priorities. Do you prefer to add the 30th locomotive to your railroad or buy a precision device that measures power, especially amps? I mention this because a lot of posts make the RampMeter sound terribly expensive when I don't believe it is the case. I agree that buying a lot of RampMeters can get expensive, but for the small layout, one RampMeter tied into a rotary switch would allow a person to monitor many power districts. Jerry Michels
