where to get rings engraved?

Where did you all get your rings engraved? I know that not all jewelers have the equipment to engrave inside the ring on the spot - they have to send it out... does anybody know of a place that can do it on the spot?

I'm in Massapequa, but spend a lot of time in Huntington and in Roslyn...

please let me know, and prices, if you have them!

thanks!
