Nice. Will be passing it in the morning heading for westfield... I would opt for a broadcom device and not a draytek given your vdsl cab type.
8924 bit old now. Try a vmg3925-b10b
Huawei cab has better options than eci. 3db profiles, g.inp as an example, vectoring (on some)
8924 may be a bit old, but if you're just using it as a modem, then I find it great. I've recently moved from a draytek to 8924 to match up with broadcom in the cabinet using an 8924. Very happy with it. I am lucky to have a very good line - max attainable rate for me is 115/25 this morning and I get 80/20 with SNMR of about 15db each way, but it's been completely solid, and the dual port setup to enable monitoring using dslstats is very nice and simple. All in all, turn everyone off (wifi etc.), set it up as a bridge, and you're good to go. And, of course, it has the added advantage of being available for about £10 on the auction site of your choice...
After a load of fiddling, i also got the voip ports to work when it's in bridge mode, it's £10 buys you voip as well...
