I absolutely recommend the Logitech G502. I've got the wired model, but I've heard good things about the wireless too.
Compared to the Basilisk, it has two extra buttons next to LMB to increase/decrese the sensitivity, but they're not at all in the way, and a mechanical toggle that allows the wheel to rotate freely.
It's easy to disassemble for cleaning with just a prying tool and a PH0 screwdriver. The only potentially destructive step is removing the glued-on skates, but those are easy to replace. Everything else is held together by screws, pins, or plastic tabs. I recommend getting an aftermarket plastic mouse wheel because the metal one is very quick to corrode.
