Trying to derive meaning from the classified posting trends is a shaky proposition. Brands that sell a LOT are going to show up proportionally more frequently in the ads. It’s not necessarily an indictment of the product at hand. Just the nature of the hobby - many of us habitually churn through a lot of gear. Sometimes we sell gear we regret, and buy back.
What IS transparent is the flavor-of-the-month cycle for trendy products and brands. When a flavor gets old, the product gluts the market for a while and then kind of just disappears forever. Prima Luna as a brand has had staying power, and doesn’t qualify for that. Their new hybrid offerings represent slightly risky new ground for them and possibly *could* end up being a flavor of the month pattern - but that remains to be seen.
