Getting Tamiya parts in the UK is a right pain.. you can call the UK tamiya importers from
http://www.tamiya.com/europe/euro.htm and they can "sometimes" get parts for you.
Don't hold your breath though..!! I tried to get some more decals ( I needed one) and they didn't have any and was told it could be two months before they get anymore..!!
Oh - Welcome to AF, and yep kiss goodbye to your free time. This hobby takes a lot of your time.
