In Dash DVD For a max?

Hey I Have a 1997 SE Maxima, and i was wondering what is a good multi-combo head unit, DVD/MP3/CD with a built in Moniter.. any help would be greatly appreciated, i have an alpine head unit right now..

before getting such as unit, I would REALLY REALLY recommend to get some CRAZY TYPE OF ALARM SYSTEM ** with elictricity, some rotwilers, hot boiliing lava around ur vehicle, and giant trolls ** so nobody even come close to ur max while u're far away from it. Seriously bro, I've seen alot of peeps getting those headunits. Few of them were my friends, I told them exactly the same thing, but the ignored me. After a week or two, their cars were broken into and those units were stolen. Seriously recomend to get a good alarm system, with some locks for the head units.

that is a very good idea being the fact that my max has no alarm whats so ever - what is a really good alarm.. is Viper good? and i saw an Alpine Alarm is that any good?!

Actuallly I have no idea which alarm is the best but if u want to u can go to Circuit City or some of the private shops where they do tints, exhaust welding and such, and ask them which alarm is the best. Im sure u will get an answer very quick.
