One of the stands I was most keen on visiting was that of Critical Mass Games, and I wasn't disappointed. Their gorgeous 15mm SF miniatures were on display on their stand, and on their fantastic display board, entitled "The Battle of Kyushu Bay".
There are more pictures on Dropship Horizon. Of course, I caved in and bought a bunch of ARC Fleet miniatures, the prototype of which I've already started working on:
At 40p each (plus a penny for the base!), they're excellent value for money! You can buy them online here.
