I'll go ahead and post this other question here, since it may be useful to several other readers of the thread.
I've been looking at the different packages you offer, and see that there are Plus, Plus II, Plus II EX, all the way up to a Plus II EX Pro with WAN. It appears that each of these packages "build" on the prior one, offering additional faetures and/or HW, correct?
My question is - although I'm sure you get cost savings by buying a more robust system in the beginning, in theory could a Plus beginner package be made eventually into a Plus II EX Pro with LAN by adding the add-ons? In other words, since I know I will eventually want all or most of the features, is there a base line package I need to get in order to be able to fully upgrade it, or are all the packages fully upgradeable?
