I doubt an immobiliser actually helps much, if you're going to throw things in the back of a van. I wouldn't expect many stolen bikes are actually ridden away. I had an immobiliser on mine when I bought it, the only time it immobilised the bike was one morning when I was leaving for work and the system failed, leaving me unable to start the bike. Cost me a taxi to and from work and a nice man to come and take the damned thing off.
I would much prefer to rely on a decent lock than an immobiliser, even if all it does it stop the opportunist thief, if the professionals want your bike enough, they'll find a way to get it.

.I use this with at least a disc lock as well.
