Depends on where you are really. I am in Oregon and there is not much in season now, which left me with canned fruit or expensive out of season berries. I went with cherries for my weizenbock for that reason. My LHBS has 3.5 lb cans of cherry puree for $10. I considered raspberry puree but the they have a lighter taste and it is twice as expensive. Your LHBS probably has extract flavoring to chose from though, if you want to go that route.
