The shop is a museum of old and extinct camera gear.
You should talk to them because they know more than you do about this stuff.
The best experience is to buy in person.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
