I finally managed to to get hold of one. The jury is still out.
ADSL1: Was rather disappointed with the results under my test conditions - on ADSL on *an ultra-long line* (63dB ds attn), no ADSL2 available at all here. Lower ds sync rate ~1600 instead of 1984..2114 using a DLink DSL-320B.
I can't say anything about vdsl performance
Note that although you don't need to do any config at all for the thing to just work, it works straight out of the box, but it appears that the device *defaults* to MTU 1492 as opposed to 1508-8=1500 according to the web admin ui.
