Just got my CM QFR Stealth with Cherry greens. Great keyboard! Great switches! I do not want to go back to any other type of Cherry switch. I have posted a complete review:
http://geekhack.org/index.php?topic=47025.0The CM QFR with greens is my latest and current favorite keyboard. Others in my collection include the following: IBM Model M, IBM SSK, Filco MJ2 Ninja TKL w/ Cherry blues, Ducky Shine 2 Chinese version TKL w/ Cherry browns, Leopold FC660 w/ Cherry blues, Tex Beetle w/Cherry blues, and Poker II w/Cherry blues. This came as a complete surprise to me. I did not expect CM to produce a better board than, say, the Filco. I tried the CM mainly as a way of testing Cherry green switches and found that not only did I like the switches better than others I have tired, I found the overall typing experience to be incredibly positive.
It would be good if CM could be persuaded to produce a sub-TKL keyboard and equip it with Cherry greens. Moreover, other companies ought to follow suit and offer Cherry greens as a standard option as well.
But back to TKLs, IMO, the CM QFR is much better than my other contemporary TKLs, including the Filco. The only keyboard in my collection that beats the CM is the IBM SSK, but it might be unfair to say that the IBM is better -- it might be more fitting to say that it is just different.
