Hi Vicious
As Gaz says, our club AMMS is a member club and we have a display every year. Lots of our guys build more than just armour and military vehicles or figures despite that being the club main theme, plus other clubs like IPMS will be there too. You are sure to make some friends.
There will be traders there as well, selling everything from kits (including one that sells pre-fondled but not built kits and aftermarket etch and resin of all types), after-market accessories, diorama products, paints, etc.
One of our club members has a book retailing business and he will be there with a huge selection of books, great reference material covering many genres as well as modelling mags and books specifically related to modelling.
If you go to the QHME website, you will see a few names of traders in the Sponsors lists, but there will likely be more.
If you are planning to put something in the competion, then the website is where you pre-register for lodgement.
