Hi all.  I have been consistently impressed with the technical
competence shown by many of the contributors, and now realise just
how far things have developed in terms of electrical "add-ons".

Being fairly new to the game, and certainly not being electrically
minded, I would find it extremely useful to have a summary of what is
available -- especially those items such as the PowerRoll -- that can
be _added_ to an existing player.  I would like to be able to offer my
customers such enhancements without going as far as purchasing a
totally electric reproducing piano.

Does any MMDer have the information to hand?  Essentially what
products there are out there, what function they serve, what equipment
is prerequisite, the cost, and ease of installation.  Is there such a
summary already on file that I have missed?

Best regards to all from England
