I'm with Plusnet, and they provide an excellent service. They're ideal for online gamers as they prioritise game traffic. Silky smooth latency all the way. Never yet had to use customer support. On the basic £15 package I'm on, the download speeds are OK but not spectacular, but I suspect that downloading will be faster on their other packages. If you go over your monthly download limit you can add additional GBs when you need them.
