Thanks for all the good advice everyone. Apologies for the delay in answering, but in odd timing, my broadband has been down all week.
I've had a look at the isp's mentioned.
Vivaciti - only the business 100 package would work - 95% of our downloading is between 6pm and midnight, and if this time is included in the peak time limits, it might as well be the total download limit.
IDNet has much the same problem, although larger limits. Their home max might work.
Zen so far looks very positive.
I could be interested in a package from a reseller, but only if I'm going to get substantial speed improvements. My modem is unfortunately not mentioned in the list, but I think I've managed to get the stats you mentioned below.
Actual Data Rate - Up Stream 832 (Kbps.), Down Stream 8128 (Kbps.)
Noise Margin - Upstream (15dB), Downstream (6dB)
Attentuation - Upstream (15dB), Downstream (25dB)
The only errors mentioned that aren't at 0 are
Interleaved Path FEC Correction - Near End Indicator 748, Far End indicator 248561
Interleaved Path CRC Error - Near End Indicator 7, Far End Indicator 422
What do you think?
