I don't post here must but I'm a huge fan of Sam's games. I've been working on a $100 Katzbach scenario using 3mm figures. The goal was to put together both sides for a Fast Play Grande Armèe scenario, with terrain and basing, for under $100. I think it came off pretty well. In fact, I need to get with it and over Blucher to try out the newest iteration of Sam's rules.
The full write up, and lots of other 3mm Napoleonic stuff, including free downloads of the scenario specific bases, and other things of interesting, are at my blog:http://1809in3mm.blogspot.com
