Golden Arrow
£1500 for two cats (plus two weeks cattery accomodation while we had a holiday). They arrived looking a little thin, but in perfectly good fettle. They settled in immediately, so they were obviously well-enough kept. This included all vets fees apart from one worming course and the cost of having them chipped (which is compulsory).
The only problem I had with Golden Arrow is that they are yet to join us in the 21st century, having no website or email communications. It's all very well being old-fashioned, but communicating with a business that is 12 hours out of synch is difficult.
