"The best way to have a numpad if you really need one, I have found, is to have a separate one like how the Microsoft Sculpt keyboard does it. "
The way I do this, is by having an 'Ultimate Hacking Keyboard' (ugh I loathe that name, how can anyone take you serious with a name like that? but at least the product itself is the best there is available (at the moment)) and then have a numeric keypad in the middle (between the two halves). I got one off Ali Express with mechanical keys, it's backlit with obnoxious blue leds, but once you let that go - it's quite a good setup.
