The Kerry King V-neck by B.C. rich has BDSM pickups, which Ive heard are bad...

What other pickups are the same size that I could replace them with?

They have been widely discredited as being fairly poor in quality. The new ones have Rocfield pickups, which are substantially better.
Personally, I would go with the new NJ Deluxe Warlock. That tribal graphic stuff looks kinda dated. No disrespect to Kerry, but it's been done to death.
