Most sets with Tsangan kits will have everything you need except the spacebar. Mix of 1x and 1.5x modifiers, 1.75x right shift and a few extra 1x bottom row keys.
Dat space bar, though.... It is a 5.5x. Good luck.
You may just have to buy a white Choc Mini. Or better yet, a Keycool 84 which has a "normal" 6.25x spacebar, but almost identical character layout as the Choc Mini, including the embedded numpad. With that set you only need to worry about the 1.75x right shift (just like the KBT Pure I use).
