Are there any? places like bestbuy and even alarm shops won't sell without installation or charge you for installation regardless of who does the labor, unless its basic alarm.. something wih code hopping, 2 way etc..

 

Sure. Plenty of places that sell Viper and Compustar for cheap online... But if you buy it online and not from an authorized dealer, you get no warranty.

 

^ What he said. Dei seems to have been cracking down on their stuff though

What you need to do is find a mom and pop shop locally and ask them to sell it to you with no warranty whatsoever. Most places won't have a problem with it.

 

are there any worthy alarms that include warranty for diy?

 

No. No reputable alarm company is going to give a warranty on something diy...

 

so warranty aside. what else is there besides dei and compustar?

 

Audiovox makes a relatively good alarm... But their instructions suck *** for beginners....
