I've been using the Q1000 for 4 years now or so, and it has been rock solid. In my last apartment i was at the edge of Qwest service (in the franklin/riverside area strangely enough) and it would cough every now and then. In my current house, since they fixed *something* on the telephone pole, i've had rock solid service. Once thing you may want to do is to set your modem up as a transparent bridge and then do PPPoE on your router/firewall. you gain an extra IP and if your isp supports it (which mine does) you get to use IPv6 natively.
