I think the setting up of inter-vlan firewalls will be their sticking point but maybe I'll get a chance to talk to one of their networking guys when I go to their showroom on Thursday.
I can do the networking myself if need be but, I'm throwing $ at this to save myself time and get a quality initial setup. @cdepaola Your point about where to skimp or not is reasonable and while i'm not convinced the 310 is the best value for the money, i'm prepared to invest there to make the integrator's job easier but I'm resistant to just tossing out the perfectly good pfsense box I purchased. Anyway... as I said you make a fair point about keeping my eye on the end product... the dealers seem to have a good local rep and they were brought in by the GC i'm using for my renovation project who i've obviously also decided to trust (but verify... as I've gotten competitive bids from another installer)
If you care, I'll report back on my experience after meeting with the installer again (i'll not give names or my location on the open forum but if you're genuinely interested you can DM me)
