Also GPS-Results.

GPS Action Replay (www.gpsactionreplay.com)
GPS Results (www.gps-speed.com)
Real Speed (www.intellimass.com)

I use only GPS Results becouse it is easy to use, have option for averaging two gt31 at same time, it is quick for view, edit, import google into it, so that is my opinion
GPSR have them all, quick and easy and cost is only 20€ for lifetime key for all new versions and updates
Don't like Action Reply becouse they works in java, so you need java runtime to start, graphics is very poor and options are more than complicated

so much from me

I started with GPSAR Pro but the more I use it, the more frustrating it becomes. I agree with MAtt and wkcwarrior on both counts- the interface is lumpy and java can lead to all sorts of fun and games (i have had to to apply for several registry keys since my system admin set up on the mac wipes any data and the software resets after every 10 uses).
I've taken a look at Realspeed and seeing it used during SpeedFortnight, I think that's probably my preferred option. Last month, I was asking exactly the same question and Kato also mentioned Realspeed was Aussie designed if that plays any part in your buying decisions.

Old salty, you may need to test to see which package has the best deceleration graphs. I saw your 28kts to zero run on Tuesday and it was a joy to watch!

Easy...

Aussie = Mal Wright = RealSpeed

I have used both and find Realspeed far easier to use.

Realspeed is great - use it for my data.
GPS Results (expired trial version) use for Google earth overlay

Downloaded trial of GPSAR Pro yesterday and have to agree with Mathew re: complexity.

PS - should I remove that Java thingy I downloaded as well from my computer.

try from control panel, add/remove programs, and find java runtime, then remove

Realspeed for me nice and simple
