In Portsmouth NH where I grew up there were 3 camera stores; each I liked for different reasons. One carried some of the interesting Japanese brands such as Miranda and Europe such as Exacta and Voightlander. The 2nd was more upscale with Leica, Nikon, Rolleiflex and some others while the 3rd was a small shop and carried Apla, Nikonos, Hasselblad and several large format brands. The first 2 pretty much split up the market with Canon, Yashica, Pentax (and the branded variants), Olympus, etc. In the city there was an amazing number of brands for a city of only 17,000 persons. After Pease AFB opened with its PX, the population increased to 26,000 and the number of brands dropped dramatically as you could buy almost all the Japanese stuff through the PX at about half the going prices. Pentax and Canon especially became standard issue. Olympus and Nikon did not see shelf space at the PX and these survived in the stores. Surprisingly, none were Polaroid dealers but, my aunt who had a discount store there (and still does) sold a lot of Polaroid.
It was interesting to be able to visit the Leica dealer who showed why if it was not Leica it was either Rollei or not worth buying for a serious hobbiest and professional. I then would walk to the Alpa dealer who showed why an Alpa made a Leica an wanna be and a Hassy made a Rollei no better than today's Holda. Obviously these guys never got along as for each it was in their blood as to the marques; not simly business. Oh, the Alpa dealer also was the Minox and Robot dealer. He felt the only lines he'd liked to have carried additionall were Exacta and Miranda.
As a youngster with a father in business all the owners were more tolerant of me being a pest than they'd be with other kids. It was like being in a candy store with too many choices and obviously not enough cash. I fell under the Leica influence and when the CL came out, I knew I wanted it. I also tried to love the Alpa but is was just not my cup of tea as to the handling, these were earlier models but the Exacta really got my attention and I also wanted a setup. I would read books and manuals and saw what guys were doing with the Rolleiflex and would dream of having one around my neck, walking down the street making beautiful b&w prints from it.
As soon as I had a few dollars in my pocket, I graduated from my folks Argus tlr 620 to a Kodak Pony 135 I purchased from the local pawn dealer for $5 and from thnere it was downhill. I learned the sunny 16 rule as I could not afford a light meter. Thankfully my aunt understood my needs and when I went to her store, she'd let me pick up a couple of rolls of film in exchange for doing odd jobs for her such as putting tv stands together or photographing some of her merchandise. She paid for the processing, also. It taught me early that the eye was the most important photographic tool as the Kodak results and I kept improving.
