If you get really interested in Flats - maybe take a look at the International Flat Figure Society website. You can either join it - or just look in as a Guest ( rather like Treefrog), though a bit more specialised.
If you scoot down to the "Vendor Area" - you will find a sub-area "Flat Figure Editors" - and in that area you will find a huge listing of "Editors Listing Updated", which I have found lists just about everything you may care to know about flats.
Beware though - it may become addictive!
Hope that will help - jb
