Alas the game itself was a bit before my time, though I'd still like to pick up a copy of the 2nd edition starter set. I have indeed looked at Prince August - sadly they have none of the things I'm looking for! I have to rely on forums such as these to do some digging (I suppose at least it's nice to have those moments where you finally come across an old gem, though).
My plan is to use them for substitutes in whatever 28mm game any local wargaming club plays - I've yet to get into the scene myself, but I know there's a fair few in London. They'd do great for IG, and a good pass for Warpath as well.
On that note, I don't suppose you can recommend any other good forums for trading areas? Lead adventures is the only one I'm currently signed up on, although with luck there's a chance I'll be getting my hands on the Jaeger squad from there.
