It may have been your recommendation that led me to use Imagestream Transport routers for some T1 P2P WAN links for my previous employer. Somebody on a listserv led me to try them as they had the features of the competing Cisco routers but were not as pricey.
Great routers, but not simple to configure by any means. They truly don't need regular restarts like some cheap routers but they are not trivial to configure, and while I'm not a hardcore networking guy I can usually pick up what I need to get the basics done. That thing was complicated to get working and I tried multiple times and I am not sure I ever got the QoS working like I envisioned it. Nevertheless they were good boxes so I would say they are a solid recommendation for somebody looking for a full-featured router but be ready for some pain if you don't have somebody handy to consult with who really knows their way around the configuration process.
