i just got a black widow secrutiy system installed for 130+50 (keyless entry) at Fry's.
one neat feature would be, start the car, all your doors lock, same when you turn the car off.
i have a 1990 accord as well...
they installed it so...i didnt have to bother, took them 3 hours on X-mas Eve.
problem is mounting the siren, i had a short ram, so they installed it where the originall airbox was (which can be a problem for when i go pass smog)
