Yeah, I had a brain slip with the 107, I meant 101-102 (101 -> 102 adds in a keyboard key that maps to a right-click context menu, basically).
Anyway, I was searching around, and finally settled on a 80-key keyboard (adds Fn key, combines some keys like Prnt Scrn with the F1-F12 keys, and removes number pad). It also has an integrated joystick and mouse buttons, which I could see myself potentially using.
Linky.
