I have ran both LK8000 and XCSoar. I have recently been using LK8000.

I use an Ipaq 3950 connected to an Garmin GPS12XL (serial cable
connection). When my Flarm Arrives I will drive it off of the Flarm.
I typically make my own mounts and cables, but am thinking about
purchasing a mount for the Ipaq.
