Ace Seeds has a cross that's supposed to be pretty decent. Pineapple Banana Bud, it was approximately $52 for a 10-pack when I looked (been a little while). It's a cross between a Hawaiian sativa (I don't know which one) and a Mulanje Malawi sativa. Supposed to be tasty, have a really short flowering period for a sativa at 11 weeks, and not stretch too much. It's on my list of "like to try, someday" strains.
