The DeLorme and Garmin are both proprietary formats that are not actually functioning in NetStumbler (NS) to my knowledge.
NMEA is an open data format. Many GPS model support this, as it is used to communicate with other devices that a GPS might be connected to, such as aircraft and marine autopilots. Check the manufacture's specs for a particular model. This is actually what most NS users are running.
I have a Magellan (now Thames) GPS 315 which outputs NMEA v2.1. It works fine. Getting a particular model to work with NS sometimes takes a bit of configuration on both the laptop/ppc adn the GPS. Read the FAQs and search through the forums for information on specific models of both computer and GPS.

What is GPS?
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
What's the signal?
GPS satellites transmit two low power radio signals, designated L1 and L2. Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band. The signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects such as buildings and mountains.
