hi Nat - i have been at concept based in king edward since jan last year. i do not have a single bad thing to say about them. my fs is dr mazzucchelli and he is fantastic (as long as you dont carry too much weight)
i have also heard that Pivet , although expensive, is quite good.

ME - had another bt today and start my 150 puregon tomorrow and another bt next thrusday 8 may fingers crossed!
