> tldr; buy uhk 80 nowadays. And an external bluetooth numpad for those days when you need to enter a lot of numbers. Why external? Shorter distance between a keyboard and a mouse — more comfortable and takes less space.

Or learn to mouse with your left hand. ;)

I used an MS ergo keyboard at my office for years with left-handed mousing since that puts the keys in the middle, mouse on the left and numpad on the right.
