I see K2's come up for sale every so often. You might also check the
ARRL classifieds and eBay.
I said that the KRC2-AC provides 99.9% cw readout. The only functions it doesn't seem to read are the tuning step, whether the VFO is locked or not, and whether you're set to VOX or PTT. That's truly all that's not read out--everything else is! Really amazing. Damn fine rig, and Elecraft is a great company to do business with.
