If you source panniers and rails, or even get the rails separately, make sure you get the bracket that attaches to the footrests as well as the main rails that run by the seat. The footrest brackets give the bottom edge something to locate onto and stop them swaying. Not all rail sets appear to come with them - dodgy sellers that should know better, usually.
Expect to pay about £250 - £275. The good thing is they keep their value (better than the bikes) so you can always sell them on for the same if you look after them.
Oh, welcome btw.
