there's a lot of stuff in the catalogue i'd like to bring to your attention but the best thing to do would simply be to ask for one yourself! i used to spend lots of time trying to find fun things to color besides what is available for kids. did the job at a great price and of course without good batteries the machine won't work. it reminds me of my family's book shelves. everything is custom made to match your exact needs. i beg to differ in some respect here. 100 miles of 2 track out of my 15.
