I can vouch for Jeff on that. He and Marten Terpstra have heard from
me more than they would probably like to over the last month. Jeff
even called me on a Saturday morning to talk about some problems we
were having and help me get them fixed.
As ISPs, I think we are all fortunate in that the router vendors realize
there's LOTS of money to be made in Internet. I would imagine that
most router vendors are this responsive to their ISP customers. If they
aren't, they probably won't have those customers for long.
