Nice work, glad you sorted it out in the end as this was well worth a look.
I didn't realise that there were promo plastics for virtually each machine; I noticed in particular that you have a Mousin' Around! flyer as I acquired one recently through eBay (I think it was $2 plus postage). I thought that as I had the machine it would be nice to get the flyer as well. The only problem with mounting the flyers like that is that you can't read the reverse side, but I am yet to think of a good way to do this myself. Maybe I should track down one for DH as well.
Is it hard to pick up the promo plastics? These would often be speaker cut-outs, would they?
