Welcome! I second the suggestion of an F-100; it will work with all of your (non DX) Nikon DSLR lenses, has a feel comparable to modern DSLR's, and are readily available in the $200 range. Also, if you're in Philly, the Calumet has a great film selection in stock to choose from. I will make the suggestion of having your film developed at a quality lab, not the local 1 hour.
