The Alchemists are really nice - I think I'd disagree with the review stating they're better than the BKP90s, but it's a close-run thing; and when you consider they're less than half the price, it's also a no brainer.
I've got a Steel Foundry set in a home-built tele, and they're amazing. The bridge pickup is especially fine - all bark and twang with oodles of character.
I'll be ordering a pair of Rolling Mills next week, so I'll post about those then if you're interested. No idea what the high output stuff is like, as it all starts sounding a bit too clinical to me around 15k, but so far I can't fault them even when taking price out of the equation.
