Keeping an eye on the QRP reflectors, it seems that KX2 mania has seriously taken hold (and Hamvention has just barely begun!). If you don't mind having a "previously owned" (read ......used) KX3, then keep your eyes on QRP-L, the Elecraft reflector, QRZ.COM and eHam over the next few weeks.
I see a few guys are already selling off their KX3s so that they can purchase a KX2. Not sure if this will become a trend, or of the wisdom of it, but then I am not yet a SOTAteer, either. The additional size and weight of the KX3 are not sticking points for the type of portable ops that I do. But for some, especially those who do long hikes, I guess it is a case of "smaller and lighter = better".
In any event, if you're looking ...... you just might find that for which you are seeking.
