Ed doesn't deal with Exaktas (Not a huge number in regular use I'm sure, and they have plenty of excentricities). he pointed me in the direction of Tom Page.

Of course I'm comparing a one man band who works from home to a company, different overheads of course. But equally if they're doing the same job (And I'd argue one bloke that deals exclusively with Exaktas will probably do a better job anyway) would you rather if you track down a good one man band or send it to a company who'll cost more.
In fairness, the strengh of a recommendation for Newton Ellis was "Their website says they do Exaktas", where as half the Exakta circle seem to sing Tom's praises.

Anyway, Can't harm to give a second place to look at, get a quote and make a value judgement over.
