When I think "regional ice cream", I make a distinction between bulk ice cream, like from the supermarket, and hand-dipped ice cream like from an ice cream parlor... and of course, sometimes you can get both in the same brand.
Here in NE PA, Hillside Farms makes a really nice hand-dipped that they supply to many local ice cream parlors. It won't be one of those "best EVAR" nominees, but you'll never get a bad scoop.
Manning Farm Dairy makes an excellent ice cream, available both in stores and from parlors. Real good. Balanced recipe; not overly sweet, nor fatty, just good, cold cream. Nice ice crystals.
Leichtmann's makes a good ice cream, both as dipped and as bulk.
For 3/4 gallons,
Wegman's store brand is an honest choice.
Someone mentioned Turkey Hill... most flavors are pretty good, except the vanilla. Overflavored.
Green's is OK, a little over guar-gummed but good.
