I'm the guy who sent Barry "a very fine set of ECW rules" (high praise indeed following ULB). Following Barry's advice (I've been meaning to post the announcement for some time), they are now available free via e-mail from my articles page...

They are in the spirit of ULB with foot regiments of three stands and horse regiments of two. The central feature of the game is a card driven turn system that adds a lot of tension to the game and causes frustration to helicopter generals. For those who are not fans of card driven systems, the game works equally well with alternate bounds, using some form of ULB's command system or even a DBA style.
All combat and morale is stand-based and there is never a need to remove casualty figures (so you avoid having that last stand of pike mucking around the table).
There are still things to add (rules for highlanders for instance), but the core mechanics seem to work well and in the games I've run they have captured the feel of the period, or at least my interpretation of it! Anyone who asks for the set will receive updated versions as they are available.
Feedback would be welcome, especially from someone who takes the time to set up some models and push them around the table!
