I did mine at Riverside Flight Centre, which I can recommend. First time pass, and the examiner even commented very positively on my flying! Did it in a Duchess, which is very well equipped.
(and her fees are only $300 now, not $350
)
Top place, if you want further info PM me.
Oh, BTW, the advantage of doing it at Riverside is that they teach it to JAA standards. They've got an agreement with Airways at Exeter to use the same checklists and standards, and from what I know most people converting to JAA IR with Airways have a very high first time pass rate.
