I also have the SPY5000m alarm, it's a lot less expensive than the Scorpion and comes with a proximity sensor. The proximity sensor is a must if you want to keep people off the seat. I first had the the Gorilla alarm which has only a shock sensor (and a tilt which is worthless on the Spyder) and I could still easily climb on the seat without it going off. The SPY5000 will shriek and flash if you even lean over the seat and it'll scare the bejesus out of anyone with hearing. I've thoroughly tested the alarm and it works great even though it only costs $99. It also comes with 2 two-way remote transmitters.
