I'm not one to tell others what to do, but if you are considering a switch to Homeseer, you might want to take a few minutes and check out Homegenie. I've been running it for a couple years and it really does work well for all my X10 stuff. It works with many other systems (not all), but can be expanded with some programming knowledge. The best part (what convinced me to switch) was the real programming capabilities. It supports C#, Python, a AHP-like simple scripting language, etc. It's not perfect, but it is really pretty nice and being free is great as well.
If you're happy with the system you picked, cool! Just offering another option if you are looking to switch.
