Welcome to Geekhack!
CODE is a great keyboard - I have one with MX clears. The only thing is that the keycaps do shine fairly easily. A lot of mine are going shiny - I just hope the black surface doesn't wear off!
If you're worried about spending too much, have a quick look at
this thread. A cracking read, by all accounts.
If you want to build a keyboard, you could also try a GH60 or a JD40/JD45. All were designed here
