Introducing new players to the game - What's stopping you?

For my group, we've settled on 4 players. I just don't have time to start another group. Our meet-up advertisement when we're short nets us players every time we have turnover, but again, the group is simply full. There's interest for sure and people have really taken a liking to the game. Our tradtional warhammer players (who played 1e or 2e) have converted more easily than people who only know D&D/pathfinder or heavens, the MMO/console gamers. They have a much harder time concieving of a character that may die, get disease, permanent injuries, insanities, curses or simply be walking around still wounded between sessions with an empty purse and it's raining.

Another thing that holds me back is that I would like to have a couple more convention friendly scenarios to play out. I'm thinking for our next campaign that I'll maybe run a two-rounder with one of the official scenarios, but most people want to play new stuff and there's a paucity of that out there.

Also: Just a short while ago (minutes actually right?), FFG posted this helpful thing on Character Generation:. What do you think of it? Would it be useful for new players to go to for their information: http://www.fantasyflightgames.com/edge_news.asp?eidn=820
