Simple Remote Keyless Entry System?

[69hugger]

My C-10 pickup has Kindig-it door handles and shaved door lock cylinders, so I have no way to lock the vehicle. I would like to add a remote keyless entry system, and am looking for the most basic high quality system.
I love Dakota Digital products, but their system has 4 channels (and hence 4 buttons on the remote).
Watson Streetworks has a 2 channel system. It has just 2 buttons on the remote. This system would be my choice between the 2 I have looked at.
I wonder if there is another brand or type of system I should consider? I don't need window or any other type of control.... just the doors.

Thanks for any suggestions!
