They are available from Sweetwater Sound (no connection to me) for about $60.  I also use the Koss SB40 ($29 on Amazon) which has a dynamic mike.  One has to be careful with the mike-to-mouth placement as it is a dynamic mike (no bias required) and thus is prone to proximity effects or boosted low end.  Taking a different approach I use a Shure SM-58 ($100) on a boom.  I did make my own XLR-3 to Foster 8 pin cable. Very easy to do and connects to the front panel MIC connector.  No bias required.  I also have used a Behringer XM8500 ($29) with very similar results as the SM-58.  The SM-58, or its like in wireless form,  is a very popular stage vocal mike.

>> One factor I've observed and stressed is "proper microphone technique".  That is proper placement of the microphone with regard to the mouth.  I find many hams have been taught incorrectly in this regard or perhaps do not understand the relationship that exists.  One needs to experiment with a specific mike and their voice in order to attain desired results.   Many dynamic microphones will have proximity effect which will make them bottom heavy or bassy.  Simply back the mike away from the mouth to correct the concern.  Many microphones have extended high end response.  This produces lots of lip and mouth and breath/nasal sounds.  Again, correct placement above the mouth, or to the side or below the mouth usually corrects the concern. And of course, proper adjustment of microphone gain and any compression is mandatory with each mike.
