On this and other forums I head Economai and Sound Value Line terms thrown out as the same. Here from my latest dealer newsletter: Probably the biggest question we get with the new Econami line is, “Is this decoder the same as what is in the Bachmann Sound Value, Athearn RTR or the Walthers Mainline sound system?” The answer is a resounding no. This value priced decoder ($79.95 MSRP) contains many of the features found in some of the higher-priced decoders, such as a full complement of sound effects (Eco supports up to 34 functions!), full startup and shutdown of the diesel engines, 4-6 lighting outputs (depending on board format), a full roster of Hyperlights (and some new ones including opposite light dim), 7-band EQ (just like on the Tsunami), F11 brakes and sound effects (just like Tsunami), and more! There are several new features added to the line, such as our new smoother and slower Hyperdrive2 (advanced motor control also supporting CV 5 and CV 6 3-point speed table), our new FlexMap technology (allowing any function to be assigned to any button without a difficult matrix of CVs), selectable sound files on one decoder (minimizing part number count and allows full customization of the decoder to the model), many new recordings (new whistles, cylinder cocks, boiler blowdown), and more. More in the letter...but...if it's a Botch sound decoder (don't care who made it...it's called "OEM" and Botch specs it) it isn't the same. Cost is the only concern, remove features until you get the cost to where we want it to be. Bachmann's goal is to have DCC on board mandated in all locomotives. When I heard that from their "technical advisor", made my future non-purchases look like a really smart thing.
