Another possible thing to try is one of the Miller integrator chips that Tektronix used in their scopes and time base modules. I seem to remember that at least one could yield 0.01% linearity. The 5Bxx and 7Bxx modules for the 5000 and 7000 series scopes are available in vast quantities, often for less than $10 (plus about that in shipping). There is also an Ebay seller that has one of the chips in lots of 10... search for "Tektronix miller". I don't know what unit those chips were from. They are in a TO5 type can, not the usual DIP package. To use a particular chip you would need to do some reverse engineering from the appropriate module service manual. The connections are usually fairly simple.
