Not a small bump in specs, really I got a 2000 lumens reading on my HD3300 while PC and PR got in the 1200 lumens level on their HD33 test units. Not sure how accurate they are on how they tested light. I showed a picture of my light meters reading ending the doubts. The shinny black case is nicer, plus the better warranty. Plus every part is hand picked to be the best, best lens, best boards everything that makes a projector it's best.
Call the AVS store for their low price on the HD3300.
