You rarely want to install a remote starter on a manual transmission car. Too dangerous, or too expensive to install all the safety overrides/sensors you'd need to make sure it worked.
Besides, most manual transmission owners are used to parking their car in gear. Aren't you going to feel like a dumbass when you do it out of habit one day, then walk out to your car, hit the remote start button - and watch the car jump over a parking block into a ditch?
I have one on my automatic car, and it's fantastic. $259 sounds like a good deal to me - but maybe it's a much more common thing in canada (in colder areas?)
