I hear there are less brittle resins these days, but yeah. If the resin
is like the resin print from Shapeways, I'd even worry that a bit of
torque inserting or removing it would snap off a pin.
The sintered nylon from Shapeways, on the other hand, is tough,
only a few bucks, and minimal hassle (except for the wait). Even
comes out in translucent white :-).
Are there another print vendors/technologies folks have had luck
with with small, finely detailed replacement parts?

It's a fairly finicky print. Fine detail and cantilevered thin pins that
need to be straight and reasonably strong.
I printed out one on a FormLabs Form1+. Came out very nicely. Shapeways does
a fine job printing them for about $4, though.
I don't know that it was much cheaper when I did it - the resin is $125/liter.
The advantage of Shapeways is you can have it made out of something
less brittle than FormLab resin. My part will work, but I wouldn't
want to drop it - the legs would probably shatter.
