The antennas can make a huge difference, especially in urban areas where multipath is problematic. You're in NYC, right? One thing to consider is the time and cost of post-processing. You need software and someone has to sit there, download the base station data, and run it every time you collect points. With a DGPS unit you get your accuracy when you collect the points and you don't have to fuss with it later. Again, knowing your budget and your accuracy needs would help out a ton in giving you specific advice.
