Just FYI, I have a used SonicWall TZ 170 (non wireless) available for sale if interested. It's a US model. I don't know what would be different other than the power adapter.

It's a 25-user model and has 2 VPN licenses. I don't know how to transfer ownership, but if worst comes to worst, I can just provide the login details for the update/software package service.

I would let it go for $200. I have attached a screen shot of the main status page.
