[Elecraft] K2 Question

[ARDUJENSKI at aol.com]

QUESTION: For those who have only one radio to use for base station and  
occasional field operations have you found the K2 to be more than adequate or 
do  you recommend the K2/100 with external ATU? I am a casual operator; both 
CW  (90%) and SSB (10%).
 
Do those of you who have or had  the K2/20 have regrets not getting  the 
K2/100?
 
Thank you in advance for your feedback
