Can't live without... probably none
Nice to have:
Inline mount w/ quick remove plates
inline swing arm bin mounts
Bin barrier for finished ammo bin (gets in the way on other bins imo)
Roller arm (if you reload more than 1hr at time, if less than 1hr it ain't worth much)
Skip the stupid press light. Looks cool, but it's worthless. Instead get yourself a decent desk lamp setup.
Not sure it's available from your listed vendors, but the camming pin and shell plate bearings are the best $30 upgrade available, imo.
Never seen that primer chute, but looks awesome! Is there a hole in the bottom so I can still run tube into a bucket?
