I’m looking to buy a set of reliable and good-sounding regulators for my uilleann pipes.
Yea! regulators are great.

Have you seen this ad:
Only just now; problem is that I’m rather happy with my drones and main stock. All I’m missing are the regulators.
order a set of regulators at a reputable maker?

I suspect there’s an element of instant gratification in the OP’s search.
Kinda.
Also, the drones and mainstock are by Seth, but he’s bowing out of the uilleann business.

I’ve an order in with Mr Childress, so I guess we can close this thread.
congratulations. I hope it’s worth the wait
