I'd like to build my first keyboard, I have a few questions

I'd like a 60%-75% keyboard with the neatest possible features for 250 dollars, I'd be using the Zealios switches when they release. I know of Ortholinearkeyboards and GON's keyboard works, are there other places to order parts from? How hard would an Atomic be compared to a GON's 60% to assemble? And I can get all of the parts to Finland without hickups? Yes, I checked the wiki. Edit: I found some build logs and building a GON now seems like something only a total psychopath would do, so I think I'll go with that.
