All switched over here too, received the Arcadyan modem, I think this is the older model. Haven't setup the Skinny modem as all works perfectly with my old Linksys EA9500, just needed to remove my 2Degrees credentials, and I think I made a change to VLAN.
Generally I dont require technical assistance, and if I do its probably not modem related, so will continue using my trusty Linksys.
Only hitch, initially was limited to 100mbps down, and 500+ mbps up, but after a quick live chat session with Skinny, they advised that I wasn't setup correctly at their end, and within minutes was receiving 900+ down and 500+ up. So if you end up with speeds which are obviously different to what you ordered, you might need to touch base with Skinny to confirm.
