My personal favorite mic for the snare is the Audio Technica AE3000. In fact this is simply just one of my favorite mics. It sounds very good, and comparable to the sm57 (just a little different of course) in most applications.
MSRP was about $400, but go for about $250-300. I got mine used on ebay for $100. I feel like I robbed the guy. It's an awesome mic. And because it's a medium-diaphragm condenser, it's actually quite easy to position on a snare. Which is one complaint I have about the sm57 (hard to get out of the way sometimes). It has a low-cut switch, and a -10db pad, and a max spl of 148db(158 with pad), all of which make it a very useful mic. In fact it's awesome on a guitar cab as well. (Although I haven't tried it, I have been told, and expect that it makes a great vocal mic as well.) If you can find one, buy it! It's just as useful as an sm57!! maybe even more...
