But I always get inconsistent prices at MS ... asked the one near Jubilee for a 46mm quoted $29. Went to the one at AMK hub, guy says $26
Try looking at the mass sale section. Usually you'll find some places with good accessories at very affordable prices. There is this CS guy called Hennessy who sells filters (collect off fu lu shou) at rather competitive prices.
Dry cabinet try SLR. Got a 36l for about $128
Dry box (Samurai F580) ... MS AMK Hub had it for about $30ish? Can't remember. Been a while.
And don't forget the B&S section! Lots of people selling various accessories. Got a few good buys from there.
