Anyone know a good place to convert FAA to JAA?

[SkyBastard]

I have an FAA CPL ME/IR and want to end up with a JAA fATPL.
Is there anyone here who has made this conversion and if so, where, how and how much?

Also, if I converted in Spain for instance, would the end result be the same as if I converted in the UK?

I plan to do the ATPL ground school in Bristol. Its the flying part I'm not so sure about.

Thanks!
