So my install was completed this morning. Think it took about 40 minutes total, which included the guy from Kelly climbing into the loft and rewiring things so that he could fit a proper master socket(which apparently I didn't have). The modem supplied was an ECI V-2FUb/r Rev B. As for speed the checker had estimated 59Mb, but speed tests are currently giving me around 70Mb - don't know if they'll stay that high in the long run but it's not a bad start.
