When I collected everything from Roy he asked what voltage PSU I wanted, after asking him which was better he said the 36V as it will run the motors faster, both the same price so I went for the 36V.

Another thing to bare in mind is that he makes the boards up to order so don't expect next day delivery. Worth the wait though!
