Hey, I'm looking to control a 5 dof robot arm using servos.
There doesn't appear to be an arduino board with 5 analogue input/ outputs (required for the feedback from the servos).
Does anyone have any advice of some add on hardware that I can get that works easily with an arduino that would fit my brief?
Thanks in advance.

You have 4 wire servos with feedback then? Not common, but adafruit has these.

Assuming you have the hardware, servos aren't driven by analog pins, at least not by the standard servo library, and there's no shortage of digital pins. (The control is by a digital pulse of a certain width.) Uno has 6 analog inputs, so you can read your 5 feedbacks, ala the sketch shown in the adafruit link.
