They ARE hot. That was exactly the point. DiMarzio got started rewinding and over-winding PAFs.
I LOVE them, but only for a certain tone. They're a touch bright, tight, and very rock and/or roll of their era by PAF standards. Good 80s dirty pickups with that tight distortion texture.
That said, for replacements you can get ANYTHING. It all depends on what YOU want, so that's like asking what your favorite motorcycle oil is. 10 people will respond with 15 answers, and pretty much all of them will be good. But only you can decide what you want.
I have two suggestions. Josh Gravelin or John Galup. In fact, I'd start with
@JGravelin since he's here on HFC. He knows tone, knows pickups, and can decipher weird descriptions of what you want and create a formula for you. They'll even look right in the guitar and his work's top tier.
John is Dawgtown pickups. He duplicated some of the DiMarzios for another member here and nailed it. If you want something close but maybe only slightly different, John is a good alternative.
If you're just looking for off the shelf we need an idea what tone you're chasing man. There are scores of good alternatives.
