Tektronix P6137 cost $400/each from Tek (no longer made by Tek but similar models cost $450-500), and were recommended for use with Tek 2465B, 2467B, 2440 scopes. Besides high DC-400MHz bandpass, they have a button that can be tasked to mean a choice of commands by the above listed scopes, eg: execute one of the auto-measures or an auto-scale or scroll to the next stored set of knob settings. While P6137 works fine with all 2400 series scopes, the ones not mentioned may not be able to take full advantage of all its features. 

I ship worldwide. Ebay requires I let you pay with Paypal. Paypal requires I ship with a carrier that provides tracking & delivery confirmation, which Airmail cannot provide internationally. 

Offering less than BIN may get you a flawed P6137 (eg: remote button inactive, or cosmetic imperfection), so please use BIN if you want a perfect P6137.
