Wish I could help but I got no PR skills. Perhaps this can provide some ideas:

10 Easy Ways to Find Black Friday Deals Online

10 Online Resources for Black Friday Ads

Black Friday Ads - The Official Black Friday 2008 Website

I also did a google search for projector + Black + Friday. If I google that, I want to see DIYPROJECTORKITS elegant 6.3" XGA Projector as the top post!

As for general advertising, get that 6.3" unit out there as a complete unit for review! Or perhaps wait to see how Luxim plasma bulb development turns out to completely knock them out

Speaking of which, saw this on Engadget (Hitachi introduces trio of ultra-bright projectors - Engadget) today. 7500 Lumens!!! Can only imagine $$$
