I found the price using TravelSupermarket, was pretty cheap for a Friday to Sat hire. A rep from the company phoned me the day after booking as the car category I had chosen turned out to not be available, for a quid extra I got a very similar car - 4dr Seat Ibiza diesel which was excellent for my needs. I collected it from Europcar. Nothing went wrong, so I can't comment on how the company deals with problems, but it was a good experience overall.
My only quibble is that the excess was 1000pounds which I guess is how they keep the hire so cheap. It would have been over a tenner extra each day to reduce that excess to something sensible, so if this bothers you then be careful how you compare the headline prices. They also try to sell you various other types of cover at the desk which I wasn't interested in.
