Hi there, welcome from Antwerp, Belgium
I totally love the Western theme: it's got gorgeous old sets to collect second-hand and lovely new stuff on the shelves in the stores.
When I started out, I only collected houses&furniture and related city stuff. Right now, it's easier for me to name the themes I don't collect stuff from.
Will you be making pictures and stuff? Do you want to collect in mint condition, or do you intend to make scenes with the Playmobil?
