Another sites I forgot to mention since I was half asleep when wrote that was kbfans. I have seen people that get into the hobby to the point of building their own get kits from them or Novelkeys. Both offer hotswap PCBs which means you don't need to solder the switches and can change them if you want. They offer 60% and TenKeyless which is probably where most people aim for so I think it's a good place to start.

Also if you want keycaps, Amazon, Ali and Banggood sell knockoff copycaps(lol) of a lot of designs for a lot cheaper. Look for "double shot" or "dye-subbed". Those are gonna last and you won't get fading legends like on cheap boards.

And don't get too overwhelmed with switch choice paralysis. If you break it down to linear, tactile, and clicky for feel and then light, medium, and heavy spring weight, it gets a bit easier to navigate to what you might want. Tactile will have a light bump or a heavy bump(popular in the last few years) but other than that, they offer testers and samples.
