Ugh, point buy. 
I understand the point of it, but much prefer dice rolling myself. If you're worried about characters not being buff enough, simply change the method a little- give 'em 30d6 to roll and let them assign any 3 to each stat; discard the rest.
I like the possibility of having a 3. Having played several characters with low stats for years (including one with a 3), I have to say, they really add character.
All that said, the 18-8 stat method seems like it would work, especially for a campaign with Heroic (capital-H) characters.
I wouldn't like it myself, but I don't think it's especially broken or anything.
