I've had MANY paddles over the years and currently use both an N3ZN ZN-5 and a Begali Expedition; BUT for portable and mobile use, I still use one of several Vibroplex "Code Warrior Junior"...it's cheap and reliable. Shop around for the best price. Bert, N4CW
For @home station work, I use my Begali Magnetic Classic paddle but for portable work with the KX2 I use my Bencher BY-1. The Begali is much more than $125 but I could put it in my will for my grandchildren’s use as a paper-weight.
