I would second that. Did ATR rating there in 2005 and they were first rate. However, whether going for an ATR rating now is a good idea is another question. Remember that Air Wales went under last year and that Atlantic Express are stopping the ATR operation before March, so the only 3 outfits left in the British Isles are Aer Arann (helps if you are Irish - seriously!), Air Contractors and Aurigny (helps if you are from the Channel Islands due employment preferences there).
That said, you can develop useful contacts with these outfits (and maybe others further afield) during the type rating.
Cheers
