Like-dislike those shops
There are frustrating shops all over the world...photo joints with wall-to-wall cameras, which may or may not be for sale. I'd prefer they not torment me. Hit camera on Avenue Road, Toronto, has a ledge all around the interior stacked with cameras which aren't for sale (Or sometimes are, according to a staff member). There is also a nice camera shop in Georgetown north of Toronto (They had negative carriers for 6x9 cm and all kinds of weird stuff) full of old cameras on display.
These 2 shops have, admittedly, nice vintage equipment for sale in designated cabinets, so I can't complain too much.
But none of this comes close to any single camera show, the likes of which we get about 6 times/year in Toronto.
The best of all were photo jumble sales held in the front yard of a retired repairman in Johannesburg. He'd put out thousands of items on the last Sunday of the month (probably still does) and could occasionally be convinced to wander into his house and bring out a Welta Perfekta, Leica, Ihagee Klapp, or special Rolleiflex. He allowed me into the inner sanctum a couple of times, and what I witnessed was...well, that's a story to go into a book.
