We're looking to move away from PFSense and CARP to a pair of SonicWall NSA 24001 configured in Active/Passive for High Availability.
I've never dealt with SonicWall before, so is there anything I should know that their sales guy won't tell me?
I'm aware that they had an issue with a lot of their devices shutting down connectivity because of a licensing fault, and they have an overtly complex management GUI (on the older devices at least), but are there any other big "gotchas" that I need to be aware of before committing a not insubstantial amount of money towards these devices?
1If you're outside the US, the SonicWall global sites suck balls. Use the US site for all your product research, and then use your local site when you're after local information.

I've been very happy with HA on all the sonicwall models we've used. The closest match to your setup is a pair of NSA 4500s in our primary datacenter. Once setup, HA has been rock solid. The one item I'd note is be sure to setup individual management IPs in the HA setup. It allows you to log in to the standby firewall without affecting the primary (staging firmware updates, for example).
