My pleasure Rob,
I'm not sure about the "W" controller problem, I think the W units 
already have enough memory already installed. I followed Carol's advice 
from her web site and have a DSR1 between my '94 model MX8O's 
controller. In my case there was no MIDI audio voice capability native 
to my piano and I added the DSR1 for the multi-timbral side before I 
even thought of getting into PianoSmart. A motherboard upgrade, if 
necessary, may be less expensive than buying a DSR1, which sells for 
about the same as a DCD1. The motherboard upgrade your dealer is 
referencing may be a software update which is available from Yamaha 
free of charge and includes the cables to connect the DCD1 to your 
controller or a DSR1 and update disks. 

As for finding a NEW DCD1 for much less than retail...that is probably 
not going to happen. I don't think Yamaha dealers can mail-order sell 
them. However, if you are as patient (and cheap) as I am, one may pop 
up on an auction site--I waited for about 6 months. The delay could 
probably be worth $700-$800.
