Any reccomendations for a non-monthly $ DIY wireless home alarm system? Ex: GE Choice Alert, X10, AAS, Ademco?

Don't want to pay a monthly monitoring fee, just an upfront $500 or so for the self-installed system (or a couple hundred dollars for installation if its reccomended). I'd like a remote (or an external keypad) and an external alarm siren so that burglars cant just break the keypad once inside and silence the alarm. Would need about 10-15 window/door sensors, and maybe 2 motion sensor for the garage/shed. And again, would like wireless for ease of installation, with enough range for a 2000 sq ft house. Many thanks in advance!
