The other solutions don't compare to a PS2 or 3 equipped loco. The costs are double or triple and nothing can really compare to ProtoSounds smoke output...or sounds.
Another point is I can take 2 of the exact same type of locomotive, PS2 or 3 one of them, DCC the other and the Protosounds one will draw half the amps of the DCC version. I've seen that many times over the years. The DCC decoders will run warm if not hot (there's a reason why DCC decoder install directions say keep away from plastic components) while the DCS decoder locos run nice & cool. DCS PS2 & 3 decoders are the most power efficient design I've ever seen....Heck the QSI Titans need a small fan blowing on them??!!
