Is/Was your 1st alarm install easy/hard?

I've seen some estimates at an alarm install at about $80 to start and up for additional features/modules.  And if I could afford it I'd add a $60 power window roll up/down module a tilt/motion sensor and maybe something else I can't think of right now but will see later and say ooooh at.         

For those who installed their first alarm or remember way back when they did their first alarm was it harder/easier than you thought or did you feel later you should have had it installed somewhere? For example did you find out later it didn't work properly or you had to take it to be 'fixed' because you couldn't get it working properly? 

I've done some wiring over the years but not much with the car's computer or ignition/door locks.  I *think* I could do it myself but don't know how long it will take me if I run into some problem(s).   

I did my first alarm install over 20 years ago. I did a very careful, neat, and workmanship like job, and It worked perfectly. I put the alarm in for a visit ot Guadalajara, Mexico. There I parked it in a large parking garage. The alarm regularly went off every night due to thieves tampering with the vehicle. The alarm alerted the parking garage attendants who ran off the scumbags.

I can't remember the name of the alarm, but it was a very good unit. About all I remember was epoxying microphones into the door jams to detect tampering. Oh and it took me a couple of days working a few hours each to install it.

Now I'm on my second install in my '99 Miata. The Avital 2200 has more wires than the space shuttle!

Ciao!
