I was looking at Zen too, but I decided on A&A.
"reasonable technical support". I'm not sure where you heard that from.
Talking to guys that actually answer the phones when they ring, know what they are talking about and know how to fix it there and then? Also, IRC support (even as late as 10pm if you catch someone in there). "Excellent Technical Support" is more like it.
Also, accounts support via IRC is outstanding too. I had an issue in regards to something, and not only did they sort it out in one go (the mistake was mine, not theirs) they did it in less than 3 mins!!
As for the peak/off peak thing. I used to be a 8-10Gb month peak user (+40Gb off peak) on Plusnet. I'm at work during the peak period for A&A but I remote in and still do some downloading of files and stuff and my usage has not even hit 1Gb/month peak.
Because of this I transfered from Max5Standard to Max2Premium and now I enjoy 832K upload for the same price, and I'm still safe in the knowledge that I've got a 10Gb buffer should I even need it.
Zen maybe cheaper, it depends on your projected usage, and the reason why you don't hear about good reviews of A&A is that we all keep quiet so we don't get hoardes of people joining - it's almost like a secret society ;-)
