All 3-letter dotcom's are at least high $XXX at the moment, and even with a "Z", this particular combination looks decent. For an end-user, you should be able to negotiate mid-$X,XXX. Good luck!
I would say it is easily high xxx to low xxxx as are most pure 3 letter .com's...historically though ones with "z" or "q" or letters like "x" "y" usually are less desirable as they normally have less potential end users and are hard to pronounce in other languages therefore reducing their universal 3 letter applicability..good luck
