Not to say there may not be overall issues recently, but I’m happy with the K3 version 2 I purchased in late 2024.

I actually have a Keychron Q6, it's hands down my favorite keyboard. The thing is very heavy.

Not sure about the quality of the Pro.

I bought my Keychron V1 Max with Gateron Jupiter Banana switches in late Q3 or early Q4 2024 and couldn't be happier with it.

It works flawlessly and I was able to swap out the switches to Otemu Silent Lime v3s (lightest silent tactile I could find, thought the TTC Silent Blueish Whites were in a close 2nd but were more expensive so I chose the Otemus in the end).

I've had trouble with the battery in a wireless Keychron.

Have you looked into building your own keyboard or finding keyboards with replaceable mechanical switches?

I know you said 100%, but for example, in a quick search I found the Razer BlackWidow V4 75 has replaceable switches.

What I ended up getting was an ErgoDox EZ split keyboard. Before deciding on switches I bought a pack of switch samples from Amazon to see what I wanted. It was great to be able to configure the keyboard with the exact feel I wanted, and have the options of swapping if a switch breaks down or I want a different feel.

Bought a Keychron and have trouble with connectivity and imthe clicky sounds shitty and cheap. I much prefer the Ducky I bought. Basically I think Keychron is over hyped and not good.

Go for Keychron k pro.

I've had:

razer

Steeleseries

Logitech

I have a Das Keyboard 4 Ultimate. I like that comes with the option of fully blank keycaps (again, this is optional). It has large media keys and a volume knob which is essential for me. Has built in usb hub and the foot bar doubles as a detachable magnetic ruler which is pretty neat. Not sure if it is hotswappable or not, you might have to look that up. I reckon it's in your price range though, and I believe they still make em despite me having mine a few years. Likely to last me a while longer, build quality is excellent. It is weighty and made partially of aluminium. I think they came out with a newer version now. No rgb or anything silly or unnecessary. Comes out the box with either Cherry MX Browns or Blues.

I have a Varmilo Minilo 75 Pro. It's great.

I have a Keychron K7 Pro with Bananas. It is a very nice keyboard to use it with my tablet on the go.

I also have a Mist Grey Ducky One 3 with Baby Kangaroos. It is sooooooo much nicer. Perfect for a work and gaming mix, also.
