Well, we have had a few problems lately which are mostly resolved now but I would still reccommend my ISP. They are 38h.com.
Pip's site, the Annexe, is on the "Mono" package and comes out at around £50 per year including domain name.
I'm running folkifo on one of the "Reseller Packages". again, that one comes with a free domain name. That one comes out at a bit under £20 per month. Last time I tried to work it out in terms of bandwidth, I am running at something like 1/350 capacity but I think I would run into trouble before that as we run a lot of conversion programs to manipulate abc to produce pdfs, transpose, etc. I think I would hit a situation of "monopolising processing power" before the bandwidth limit was reached.
