I'm going to be travelling and doing a deal of field recording, both interviews and some instrumental recording. I'm trying to be as portable and efficient as possible, so I was thinking of buying the following Zoom H4N Shure KSM141 Shure SM57 Does anyone have any experience with the H4N? Everything I've seen from it has generally been positive, so I'm hoping for the best. The fact it can be used as a USB interface is positive for me too. I liked my friend's KSM141 and SM57 mics, they seem like they can cover a lot of recording ground.
