Maybe separate out by categories:
Specialist resellers (Mim, HMS, SUS, etc)
Luthiers & manufactures (Antika, Bonanza, Mainland, etc)
Warehouse stores: Sweetwater, Thomson, (Amazon, though I’d not include them in this list)
You’ll get very different experiences from each set here. I’d steer anybody who didn’t know what they were doing to the specialists and some of the specific manufacturers.
The warehouse stores won’t give a novice useful help and are best for people who already know what they’re doing. They warehouses also don’t need the marketing boost for people to find them - for the most part people who need this list are best served by being made aware of the non-warehouse options.
