I remember one or two years ago, somebody had posted here showing his home made M49 for if interest, don't know if you remember that one?, all brass with the Microphone U shape shockmount iirc etc.. etc..., descend job, the grill mesh and form seemed to be "as original", can't find the post tough...
His was also pretty expensive when people asked about it, about the same ballpark, but i don't see how it can't be for small quantitys, it's just impossible to bring it down, talk about a thousand and then of course price would drop. EDIT: of course there is the China option + the headache, but that wasn't Riggler's tought i thinK.
Anyway will see, but i might pass as well :-\
