We did look particularly at Moen based on the recommendation of the guys
at the plumbing supply house. They said that they preferred Moen and
Delta with a slight edge to Moen, which is why I was surprised when it
was not my work that leaked but the faucet itself. Meanwhile the 20
year old Delta is still working fine but doesn't have the sprayer nozzle
which was the whole point of the exercise.

I've not installed a recent Moen, but I'd be _very_ surprised if it's a
generic design defect. I'd check first of all that the installation was
actually correct (maybe if it's somewhat unusual the order of rings,
etc., might be wrong?) or there's a piece missing or something similar.
If there were a generic problem, you wouldn't be the first. If you
can't figure out the problem, take it back to the supply and find out
the cause.
