Foreester XT upgrades ??
I would have to say compustar, from everything i've heard on this board, they seem to be the most used, and they have two way remotes (which can tell you what your car is up to) which work up to 1.2 miles. i have heard from a dealer that installing the remote start can mess with your transmission (but that might just be if you forget to put it in neutral) i am going with compustar, and from what i've read on this board, their alarms seem to be incredible.
