[size=large]Not a lot to be concerned about with the CTX since it will be covered by warranty. The way the owner has taken care of the detector is another factor though. A customer's honest viewpoint of the conditon can be totally different. One customer may have a "dog" and call it "in good condition" while the next customer may have a mint machine and it is mint. Pictures before the purcase is good especially a couple of good close-ups of the display from different angles. Too, a picture of the handgrip tells a lot, as to usage.
Pricing can vary but I have found the area of $1700 to $1900. Hopes this helps.. Richard[/size]
