That'll only work in the States where they have a ground based Crowd GPS network and 100 feet range may be OK for finding your keys but no good on a bike. The others can be had for anything from £20 up to about £100. They all use satellite based GPS, or at least all of the ones I've seen, the chipset is so cheap these days and it's a lot more accurate than GSM locating. Some will only work with a 2G SIM card which are getting difficult to get hold of, others will work with any. Some will store the last known location, so if it's in a lockup or container, will still tell you were it is (or at least, where it was when it lost signal) as long as it can still get a GSM signal. Rather than go for the cheapest, find a UK based supplier and ask them. If I was going to fit one to a Fazer, I'd put it under the inner fairing plastic bits either side of the tank or in the tail. The magnet wouldn't work but a bit of stick on Velcro would do the job.
