I don’t have an 1800, but I do own a fully modded Q3. With that being said, I just purchased a Monsgeek M1 as the build quality seems to be as good, if not slightly better, than the Keychron. It’s still in the mail, but from what I’ve seen online and read, they are fantastic.

The extras that Monsgeek has compared to Keychron are: switch pad foam, tape mod, better gasket mount (silcione, keychron is foam), stabilizer pads, interchangeable plate (comes with polycarbonate), and it’s $60 cheaper.

I buy all my cables from Mechables as well.

I’d spend an extra $20-$30 and get Akko keycaps. They are some of the best keycaps you can get for $40-$50.
