Keychron C3 pro 40$CAD on FB or recommandations cause I'm lost

I saw a Supposedly new keychron C3 pro TKL that has some light dust on it so probably barely used for 40$ Canadian.

The price for a new is around 80$ on Amazon lowest price seems to be around 70$ + 15% taxes where I live.

On paper it looks like a good deal but it's not hotswapable. I have a very garbage keyboard not even worth mentioning what it is. Anything would be an upgrade really.

I've been looking at keyboards prior to blackfriday but could not decide what to get. I've looked into HE keyboards especially.

I'm looking for a smaller size, TKL or smaller for fps ergonomics even if I do like having a full sized keyboard.

60% seems a bit too small for me but I'm not totally against it. Having the delete key and seperate F keys seems nicer. I don't care much about RGB but I would ideally want the keys to be backlit. I could make an exception though if I'm at least able to see the keys without having a Christmas tree under my eyes.

The keyboard world is too complex. I am not willing to spend too much so ideally anything under 100$CAD including the 15% taxes and shipping... I could maybe go to 120-125 if it's really worth it.

I've never used linear keys I'm scared it would feel too weird but I guess I might have to try some day.

So between keyboard sizes, Switches feels and technologies HE, mechanical, backlighting, software support, wireless non wireless... I'm just lost.

Fun 60, Madlion HE68, Aula F75, epomaker Amazon AliExpress (always confused with the prices since I don't have an account) maybe a keychron C3 pro for 40$ cash near my place might not be a bad idea but I don't really like the keycap colors and it has brown switches by the way.
