The S.A.E. size 3 Zeniths (and Strombergs) are sufficiently scarce that the commercial rebuilders cannot find cores; thus don't generally offer rebuilts.

These have been extremely popular with the antique car enthusiasts for several years to replace O.E. carbs from the early 1930's.

The carbs are available; but not in the price range most wish to spend when they are used to Rochester pricing.

As far as rebuilding yours: do it! Kits are readily available, and the carbs are MUCH easier to rebuild than the Rochesters. There are a couple of possible issues concerning both stuck accelerator pumps or the pressed in check valves; but both are easily overcome.

The most expensive carburetor is the wrong one you attempt to modify.
