We have been running JLap at our club now for a few months.
The Good: It has just about every feature you could want, supports the AMBrc personal transponders, and the developers provide about the best support you'll find for R/C scoring software. The graphical race print outs are very nice, and it scores laps down to the thousandth of a second, which is pretty cool.
The Bad: Finding the afore-mentioned features can be a pain in the ass. The interface is rather clunky, and various modules of the software override others in a very non-intuitive way. For example, you can set max cars in a heat/main on a class-by-class basis, and that overrides a particular event. So if you only happen to get 8 racers in a class, and your class max is set to 7, it will sort a 7-car A main and 1-car B main; there is no way to change that without re-setting the class for each event. There are also still some lingering bugs in the system but they are being worked out quickly.
Overall, it's a quality product and we're happy with it. The learning curve is VERY steep compared to Autoscore. If you spend some time learning it, you'll be fine... just don't expect to fire it up and have everything run smoothly the first time.
