Burstbucker Pros cost $490 or so at Sweelee for a set. Moving on, good combinations for an LP include:
1)59n/59b
2)59n/Customb
3)PearlyGatesn/Custom5b
4)Seth Lovers set
Tone is really subjective, so I would recommend that you read up on the abovementioned pickups, the Seymour Duncan forum is a really good place. HC reviews would do as well.
