[Elecraft] KAF2 or KDSP2 for K2?

[Stephen Roberts]

Well going from a rather ancient Ten Tec to a K2 has been a real treat for sure, and as most of us can't seem to be able to leave anything well enough alone, I was thinking about possible options I can add without breaking the bank. Can any of you folks tell me the real life difference between these two options and whether or not either one of them is worth the expense? I do almost no voice...all cw.

Thanks!
