Are Moss, B&G, MGOC parts equal in quality ?

["Ricardo Sal Monteiro" <ricardo@det.ua.pt>]

Hi,
    I need to get a interior mirror for my MGA, and I was thinking from were
to order. Since the prices from B&G and MGOC (for instance) are different I
guess the quality and appearance (finishing) should also be different, isn't
it ?
I would like to know your comments about differences in parts from MOSS, Brown
and Gammons or MG Owner Club Spares.

Thanks
R. Monteiro
