At the moment ebay.de is flooded with Cisco 871 routers. This means they are getting cheaper; recently they sold for less than € 200. Perhaps it is time to get one.
Draytek's german support has answered my questions about the DrayTek Vigor 2130. Show stopper for me is it can have only one /64 on the inside. Minor points: DNS and NTP are not supported on v6; no RIPng. Everything else is there, so still an interesting device for the more common SOHO settings, I think.
A very cool idea is a live demo of the web configuration gui of the 2130 on their website.
