The dealer experience: stereo, cameras, table saws, anything involving good, better, best, fantastic is and has always been subject to the level of acquired knowledge, seller and buyer, and showroom experience.
Newbies, unprepared, then and now, are like fish in a barrel. And they are looking into a huge pandora's box, often talking to the Pied Piper of the moment.
I'm 71, I grew up during the growth of the industry, NYC: late 60's; 70's; 80's. My office was on 44th, 1 block from Stereo Alley (after it moved twice). Harvey's was the premier store 45th and 5th ave. Others scattered around the city. Leonard Radio was in the ground floor of my building, the original Hammond Organ showroom.
A few dealers around me in NJ, the closest Stuarts Audio still going in Westfield.
My acquired knowledge allowed me to know if a salesman (no women then, or now that I have met) knew what I knew, and more, and if truthful. You became friends, ..., my friend Wayne at Harvey's used to call me when a nice piece came in on trade so I would know to watch the used shelved in the back. I still have Carver Tuner, Carver Cube, Tandberg Receiver, Velodyne Subwoofer. My friend Phil at Leonard's called me when Ray took in a pair of JSE infinete Slope Model 2's that he knew I absolutely loved. Together we hustled them out of Ray's grasp into mine.
Other showrooms around NYC, rarely visited, the experience was NEVER great, but varied from pretty good to very poor. None of them had any respect for my knowledge or knowledgeable questions. These were ones I had to block out some time and travel to get there, so the disappointment was magnified by that.
Stereo Exchange was and still is a good experience, They rely on you knowing what you want, or might want based on their stock and prices. More of a flea market of quality stuff only.
Original 47th Street Photo, when it was upstairs on 47th street, was basically "Come back when you know what you want!".
Today, fewer dealers, an enormous myriad of choices, much harder to educate yourself about it all, (same for salesman), and the unlikelihood of becoming friends by repeated visits, makes it a whole different world.
Good luck to us, heaven help the newbie.
