1+BR Near Grand Central?

I am looking to rent something within walking distance (7-8 minutes) of Grand Central. There are so many options in the area (Metropolis, Vanderbilt, 425 Fifth, The Buchanan, 230 E 44, Archstone Murray Hill, Paramount Tower, 212 E 47, the Nash, etc) I am a bit overwhelmed. I'm not a stickler for amenities (the most important for me are high ceilings and nice finishes. and I guess FIOS). I'd love a spacious 2br/2ba in a townhouse or brownstone just as much as an ultra lux 1br in a doorman building, so I have a lot of flexibility. (Budget is 3-4.5k, with some flexibility). If anyone has any ideas, I'd really appreciate it. :)
