Good! More is better providing these are of the same quality or better than the Tsunami's. I'm finding there is quite a broad spectrum regarding the quality of DCC Sound decoders, more seem to be towards the lower end but the prices don't seem to reflect that.

If one could roll back the hands of time... They would be waiting for the next train into the future. A. H. Francey 1921-2007
"Unfortunately there are individuals who have migrated from other railroad sectors that have a reputation for litigation and piracy. They have an eye for grabbing a portion of the scale Model Railroaders market. They are attempting to litigate based on the above patent which will eventually be invalidated. Hundreds of thousands of dollars and numerous man-hours have been directed at preventing a hostile attempt by the high rail group to control our hobby.
At some point in the future when we have no legal exposure we will reveal the identity of these unwanted migrants, you will be surprised who you are sleeping with and of course you will have the power to act accordingly and limit their opportunities."
Interesting. The above quote from QSI suggests that we may be doing business with these people.
