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.
