Yes - the differences between Entanet suppliers are marginal. And for your requirements Enta is the place to be unless you want to take a big risk on Talk Talk. You may need to do a bit of download scheduling as it isn't unlimited, but not many people find that a problem.

Entanet regularly add large chunks of extra capacity (622Mb at a time) as they are expanding phenomenally. The downside is it takes time to get - therefore some Centrals (a 622Mb piece of equipment) get overloaded and an Enta system (ALT - anti-loss-tool) comes into operation on affected Centrals, so the speed on those goes down in 500Mb steps but never below 2Mb. If it worries you, you dis-connect and re-connect and hope you get on a lower-loaded Central. Loadings are available on line.

Go for it!

I don't need all that capacity, so I am on Newnet - one of the best ISPs for customer satisfaction and high speed stability - as their pricing structure deflects the heavy downloaders - Enta attracts them. You said you wanted unlimited .

If you're looking to download a lot and want an "up to" 20mbit service, you should go with Virgin Media.
