Scott Data delay devices (http://www.datadelay.com) also do programmable delay lines their minimum order is $US75 which isnt too bad particularly if more than one sawtooth corrector is to be built. They even do ECL programmable delays as do Micrel (http://www.micrel.com). However these ECL programmable delay devices dont have enough range for this application.
If you solve the multiplexer problem and use embedded calibration you could use circuit board traces to implement the delay line sections, however a lot of PCB real estate would be required. Such delays also have significant tempcos when using fibre glass PCB substrates.
