If they would price the boards ($200 DCS Upgrade Kit) closer to say$150 then I'd upgrade more of my PS2 engines to PS3. As it stands now I can buy a nused PS3 Railking engine for around $200 and cannibalize the PS3 board for one of my Premier PS2 engines. PS3 gets me DCC and a better sound set including a quillable whistle on steamers. With no more new MTH engines after 2021 upgrading PS1 may be the only way to get a certain engine under command control. A reduced PS3 board would make upgrading fiscally more attractive and generate business for upgrade techs and expand DCS user base.
See my PS3 upgraded 1997 C&O Allegheny here: I bought the engine nused for about $350+$200 Ps3 upgrade kit (DIY install) = $550 for a Premier articulated steamer.
