Samson Q7 is also a great alternative, beats the Shure SM58 by a wide margin, great noise reduction, outstanding feedback suppression, and sells for about $60 at most online stores. When I was using a hand-held mic the Q7 was always my favorite. I sold both SM58s for half what I paid for them, and one was never used.
And, like DomM, I haven't had any experience or ever seen with the mic you posted.
Good Luck,
Gary
