Maybe wait and see what you think of the stock keys before replacing them. A lot of people who call them trash have quite 'refined' tastes, which they have garnished over time and from experience. As this is your first mechanical, you may find that you don't mind them so much!
My current keyboard's keys get stuck and are often hard to press down. Anything that really doesn't get stuck is fine with me. In comparison to keyboards I have used, like keys that are textured rather than smooth.
Perhaps I will consider sanding the QFR stock keys when necessary.
I have an idea of having black keys with bright green text but having the modifiers as bright green with black text, similar to the Toxic set. I just can't get over seeing it as yellow or green.
Is there anywhere I can get this done? It's really inefficient for me to have blank keys as a graduate student, even thought they look sick.
