We have been using Trimble XT/XH for years now, but we are at a time when we need to upgrade and do not want to drop another $8000 for another Trimble that only causes us headaches and not very user friendly. We have begun using the ESRI collector App and Garmin Glo for some of our projects that don't require sub-meter and everybody seems happy with it. However, since we can't post-processes this data it won't be submissible for some of our projects that require documentation stating the data's accuracy level (e.g. wetland delineations).
From what I've gathered from the research of the newer sub-meter bluetooth units, they are capable of real-time differential correction, but the data can't be post-processed like Trimble Pathfinder/ESRI GPS Analyst. Are there any units that will do both real-time differential correction and post-processed differential correction?

I have been researching sub-meter bluetooth recievers that can work with Collector, and found the Bad Elf 3300 GNSS Surveyor might do the trick. They claim 10-50cm accuracy after post processing: http://bad-elf.com/pages/be-gps-3300-detail
Pair that with a decent tablet running Collector and a lifeproof case, and you have sub meter data collection for under a grand.
