C&C and CS between 29-35 feet fall in your budget and are both common enough and seaworthy enough on the east coast to command a range of prices. There are Viking 33s down there that are a tad more racer than cruiser, but built well by Ontario Yachts.
I think a Tanzer isn't a sea boat and their boxy cabins mean little or no side decks. Hughes made good cruisers that could race and are seaworthy. "Comfort in a seaway" is going to be a factor for you even in coastal Atlantic conditions that it isn't on the Great Lakes, where tall rigs and light hulls predominate that aren't always the best idea for the ocean.
