BK's will bring out the best in any guitar (and amp for that matter). The upside is that if you decide to upgrade the guitar you can always swap the pickups into that.
As for value for money, that's a personal opinion, BK's will give you a good improvement over stock pups, but as to if it's worth it? Only your ears will answer that. So far for me, every time the answer has been yes, they are worth it.
