My good friend Bill is kidding here, of course, but he knows what he's 
talking about. To understand mics and audio for ham radio, check out 
my tutorial, which shows the real reason for the rising hi end 
response in a 444 (which is what they did with the SM58 as well, and 
for a similar reason).

If I lived outside the US and wanted to buy a good mic for ham radio, 
it would be an ElectroVoice RE11 or RE16. These are pro mics, so they 
don't have PTT switches, but they sound great on good ham rigs. The 
tutorials show how to wire them and how to use them. In general, good 
quality dynamic mics last forever unless they are badly mistreated, so 
it's pretty safe to buy them used. 

The discontinued Shure SM53 and SM54, aand AKG D202, D222, and D224 
are equivalent to the RE11 and RE16. Of these, only the RE16 is still 
a current product.
