Thank for the reply Jim,

Just to clarify (because I seem to understand it even less now) - you drew the red box under the UltraPak+ column - but I'm interested in upgrading from Pro to the UltraPak (no plus)..
Are you saying that the extra price bump from UtraPak to UltraPak+ would be necessary even if I want to end up with the non-plus version?

Thanks, Rocky.
