[Elecraft] k2 accessories questions

[Gary Lee]

Getting ready to order my k2.  However, looking to save a few pennies.  So
requesting opinions.

1. knb2.  Necessary?  also impressions of usefulness, and amount of use.

2. kaf2 same questions as above.  I have little experience with audio
filters, accept for the one included in the emtech kits.
3.  hand mic.  Forget the model number.  I have a spare handmic for my
kenwood ts2000.  Would this work, and if so, is the heil a big improvement?
 I have always gotten good audio reports on the ts2000 with the stock mic.
This is what I would use on the k2.

Thanks for the information.
