I just got my Graphex (X) shutter back from Flutot's camera repair-works just fine and I have the corrected speeds all spot on except 200 is 150 and 400 is 200. A small fix to my cable release (posted elsewhere) and all is good. Due to troubles getting my M-M/X shutter to work I elected to donate it to Carol's parts bin so she only charged a CLAC for my X. Wait times may be somewhat erratic as her Husband is quite ill, so check before sending anything.
