installation depends on the shop and the car.(the quality depends on the shop!!)most of the alarms I sell (mongoose,viper,python,cyclops and quiktrak) start form $390 and go up from there. in the case of quiktrak that one is 2k fitted with one year monitoring.
howhow,
what model was yours? (curious- I did a customer call to a local autobarn here and was told $500 for a hornet system.)
re the brant alarm. I would ring brant direct in your area. (form memory its $1000ish-I haven't got my books in front of me.)
for timers all alarms can be wired around them - dont let any shop tell you they cant be. 3 minutes is plenty of time after a HARD run. 1 min is normal for most of the cars I have seen/worked on.
