I assume you mean carrier-phase enhanced methods (RTK or post-processed) and not DGPS; DGPS is a pseudorange-based method that won’t get you much improvement over WAAS, which is built into most GPS receivers. I don’t really follow GPS chipset releases, so I don’t know if anything interesting has been released in the past year. However, until consumer-grade dual frequency GPS receivers start becoming available, I don’t expect any groundbreaking improvements from new chipsets. What I detailed in this post works for me, mind you it’s far from a plug-and-play solution. I should also note that you’ll only get sub-meter accuracy with a clear, unobstructed sky view, such as in the middle of a field (at least not without a long static integration).

I’ve tried using a SiRF III receiver and was only able to get within .7 meter, which was not that great.
Considering that over a year has elapsed since you posted this article, what is the best hardware / software combination you would recommend? I would like to do this for under $100. I live only 12 miles from one of the Washington state GNSS stations (BDRY) at 48.98669397, -117.349909.
