The Samson Q7 turned out to be one of my favorite mics, and $29 made it a no brainer.
I don't care for a tinny mic, too bright and always feedback problems.

The Shure 58's were popular... not because they sounded great but durable ( girl singers can drop them all day long and they still worked).
There were plenty better mics then Shure, I preferred the Audio Technica mics. I still have a matched pair of custom PR60's.
