I just checked the most recent two dozen keyboard releases on drop. Not a single 100 (or larger) in the lot
I just checked to see what drop was and I see it's for keyboard enthusiasts, but they require javascript and I'm not interested enough to enable it. Either the purpose of the site is to sell tracking info or they don't have anyone who knows how CSS works. I don't know why I would care about the latest keyboard releases, they are irrelevant to my purchasing decisions as what matters to me is what is available to me someplace I want to shop.
That aside, I do most of my electronics shopping on aliexpress now. They have been responsive when I have had issues with purchases, and the prices tend to be much better. The keyboard I'm using now (which is a redragon k556rgb) is stuffed with outemu silent peach switches* I bought on aliexpress. I just got an ajazz ak820 from there. Since pretty much all of the keyboards are made in China now anyway, that's the cheapest way to get them. Their search engine is trash, but their site otherwise actually works these days so that's nice.
If you don't want just any 100%, and instead want certain less common key switches or a specific theme or other less common features, it can be hard to find a 100% that has them.
I wouldn't plan to get a keyboard with specific switches. I would plan to swap them, or buy one that came without switches. There are just too many switches out there for all the switches you might want to be available in keyboards. I have two k556rgbs since one LED died on one of them and they sent me a replacement, now I have a shitload of redragon red switches I'm not using. But it's only like $22 for a 110 set of outemu switches.
* I spent thirty bucks or so on switch testers first to figure out which switches I wanted. Outemu is so far the only brand I've found with feel equal to genuine Cherry, e.g. Kailh and Gateron are both hilariously sloppy by comparison. In side by side testing the difference is immediately obvious. Their "silent" switches are also quieter than other companies'. Do most keyboard enthusiasts just read reviews and skip the switch testing step or what? I see people gushing over Kailh all the time and I'm like, buh?
