i went once to that church for a session ... the mike he used
didn't look too different from any other mike leh ..
how different can a mike look? 
SM58 is the performance industry standard
SM57 is usually used for instruments, it is also "used on the
lectern of the President of the United States. The microphone kit
(two SM57 microphones, windscreens, microphone stands, and black
right-angle XLR cables) is available online for $500, and is
referred to as the VIP/high profile microphone kit.
The SM57's retail list price is $99–$160[2] in the United States and
£65–£105 in the United Kingdom"
the church budget is so much because they can afford things that
they don't need.
