You can spend $50 or 5 figures. What price range are looking for? In the bargain bin, I like my MXLs (quiet, do a good job, inexpensive). I have used an AT 4040 and liked it as well (still not terribly expensive, and I wasn't comparing side by side, but it seemed a bit more mellow).
I would think single mic is tougher to do than it looks. It takes some good choreography to keep the balance right. If I were setting something up like that for regular use, I might have a couple other mics set up for single instruments that need more help (like guitar or maybe vocals). I'd also have a dedicated channel for the bass.
