Budget and preferred layout will play into this a lot, but generally these days it's not too hard to find wired-only and hot-swap. Anything else you can tell us?
If that $200 is for the barebones kit, then the QK100 would be right up your alley. It's an1800/96% style but leaves a full-size numpad zero. It also has a ton of options, including a wired hotswap PCB and choice of FR4 or PC plates, among others.
Check out the gmk67, it's a 10 keyless and no F buttons size, but is hotswappable with a typical switch plucker/puller. I think multiple "companies" make and sell it, but I found mine on alliexpress for like $35. It does USB, Bluetooth, or 2.4ghz with a USB dongle that stores in the back of it. I put in Akko Lavender switches in mine and absolutely love it. The base + switches + keycaps total only cost me about 75$ for a fantastic, quality feeling keyboard.
Can also grab a PCB + case for a 60% if that's up your alley. Not exactly a kit but you can definitely put the parts together. Note that if you want more than a 60%, most PCBs and cases must go together.
