When I read your post it jogged my mind and I went looking for a video of the Grand Opera organ and actually found one which I listened to a few times.
The organ on youtube didn't sound all that great but at the same time it didn't sound all that bad, either. I also found a Viscount for sale (2 manual) that had four years of warranty left for $4200 and change. This ad makes the Wurli I've been talking about seem a little over pricedandArie V's post elsewhere seems to re-enforce that idea.
Thanks for the reply.
