The SM57 and SM58 shouldn't need any introduction.
Essential microphones in any serious audio professional's inventory, these guys are legendary for their extreme ruggedness and familiar sound character, and Shure knows it, they've been making these since 1966!
Note of caution: Due to their popularity, there are many counterfeit SM58 and SM57s in circulation. Would be good if Massdrop can get these legit from Shure and at bulk prices, everyone doing pro-sound could use a few of these.
Seriously, I already have 10 of these combined, but one can never have too many SM57s
Here's President Obama delivering a speech with SM57s (with attached windshields):
