I have pairs of 4061's and 4090's, which are about as sensitive as 4060's, and I usually run my mics through a Naiant Littlebox into an M10, or directly into a Roland R-44. I tape at nightclubs and small venues, never stadiums or arenas, and usually put mics on stage or at stage lip, and I've had no problems with either the 4061's not being sensitive enough, or with the 4090's being too sensitive. I avoided the potential pitfalls of buying 4060/4061's that may have suffered stage abuse by buying a used SMK4061 kit; my reasoning was that whoever bought the whole kit was probably a taper, or some kind of recording engineer, and would have been better motivated to take care of the gear. As it turned out, my kit was in excellent condition and it has served me well. It also cost $500, which is about what a pair of 4061's goes for without all the accessories. Those accessories are not cheap when you buy them separately; most useful for me are the XLR adapters and flush mount rubber disks. At the time, the seller had several of those kits, all for the same price.
