Eisenhower in Crownsville would be your best bet. It is in decent shape right now and the greens fees are reasonable. I would not recommend Bay Hills in Arnold, as they are more interested in quantity rather than quality and it gets very backed-up.

If you don't mind paying more, then South River in Edgewater (which is turning into a private club by the end of this year) or Queenstown on the Eastern Shore are both highly recommended.
