Small Office Phone System

[5porthead]

I'm needing to replace our Panasonic A-309 phone system with something new. We have 2 lines on the one number and just 4 handsets. Can anyone suggest the best place to look for something that could be installed by myself fairly easily.I'm not that confident with wiring and there seems to be a lot of wires and boxes on the office wall. Help please.

Thanks for the very quick replies. I'll look into the options above. We don't need any extra features but the system seems to be having difficulty when we try to get a line and dial out, sometimes takes 2-3 attempts so I assume the "box" is on it's way out. Fair point about paying someone to remove all the old system and install the new one the wires do look a little daunting.
