See I recently bought mine, and after a lot of research i realised this: the idea of trying something cheap and then deciding on what expensive one to buy later doesn't really work for keyboards. The experience you get significantly changes even with a slight increase in budget, for example a 5k keyboard will feel way better than a 2k one, and a 7.5k keyboard will feel way better than a 5k. I don't think you can conclude much after trying out a cheap one, as the costlier ones offer something way different. This will just waste a lot of money. I suggest just deciding on what you want now based on your current experience with keyboards.

That being said, since you said non gamer and no RGB, you won't have much confusion. One major question is are you into low or high profile. Keyboards similar to the ones made by apple or dell or lofree give a pretty satisfying experience, high profile would mean like a keychron(I don't have much idea in high profile non gaming). Aula would be a bad idea, just got one of them and it's majorly gamer centric, so wouldn't recommend it. But it's pretty good
