actuator and alarm install

hi, i have a 97 civic dx. i've done the how-to on the fuel cut off... excelent info!
I would like to add power door locks and and alarm. what do you think of the 2-door generic actuator kits on ebay? what's the difference between 5 wire and 2 wire actuators? how hard will this be to install?
all i need is a basic alarm / keyless entry combo. any recomendations under $150?
