I agree with QNH 1013 and others re. Atlantic Flight Training. Did CPL/IR with 'em and the level of instruction is second to none. Even now, after I have left, they still have time for me when I drop by to ask questions/advice etc. or to borrow Atlantic 43 for an hour... I didn't do ATPL with them but I saw some of their mock exam papers and they were damn good.
As QNH 1013 recommends, the best thing to do is to pay them a visit, and you'll probably be impressed.
Cheers
