I’d look around for the real thing. If you are patient, you can often find great deals on used Alembic pickups and electronics.
I think he makes good stuff. The prices go up and down, so if you time it right, or make an offer, you can get some stuff for a decent price. I got a spare Series electronics board from him and it worked perfectly and seems very well made. He uses very high quality parts. I have no idea about his pickups, though.
