Any suggestions for a good high-hat condensor mic? I am thinking about using a small-diaphragm condensor, but I am open to any other suggestions. My price range is about US$500. This is not a mic I will use very often for high-hats (rarely will it be needed, but when it is needed, it *is* needed!). It would be nice to obviously use it elsewhere as well, but I don't want to rob the bank to pay for it since it will be a sparsly-used mic. I am thinking about maybe getting an old standby Shure SM81, or possibly an Audio-Technica AT3031, or AT3032. AKG has the 451, but I am not sure how it would sound on a set of hats. There are obviously several possibilities here... although I know I can't really go wrong with an SM81, I was just looking for any other suggestions. Thanks!
