I was in Charles Ro yesterday picking up some Christmas items for around the house and one of the accociatss demonstrated the new Thomas Kinkade RTR Chistmas set. I thought the sound was pretty decent for a set in that price range. Not Legacy quality of course but very good never the less! I was told there was no volume adjustment it was just on or off. While at a train show or other public display that probably wouldn't be a problem but at home in a much quiter setting I think the volume could get old quick!
I'm not sure if the lack of a volume adjustment is the same in the whole line but a simple volume pot would be a nice option to have.
