Has anyone used Nassau Radiology for their level II sonogram?

I have a strange question. I have to make an appt. I know they offer the 3D sonogram so I mentioned it when I called to make an appt. They told me that they do it 2X's a month and to call back later this week when they make their schedule.
I was wondering if anyone went there for the level II and they were given a 3D sonogram without asking for it? They told me it would cost extra. I don't really need the special doctor to do advanced sonogram. I just want to sneak a peak at the baby on the 3D screen.

Any help would be appreciated!
