I'm using the default 22 point buy but with the addition of this little house rule. One of my players asked if he could do that when everyone was first making up their characters. I put it to a vote and the group all agreed.and you can drop a 10 to 8 for 2 more points
I did a 36 point buy (and max hit points through 5th level) in my last 3.5 game and even then the PCs were getting their asses kicked (I was running them through the Red Hand of Doom). The PC mortality rate was very high.
Depending on how lethal 4e turns out to be, I might increase the point buy above 22 but I doubt that I'll go all the way to 36 again.
