customer service sucks untill you can get to stage 3. they are very good. the router isent that great in my opinion i had to change it 3 times in the end to get it up and running, but i am guessing that whoever you go with you may or may not have the same problem as it seems the netgear range is popular with many isp's.
speeds in general are good for me. for the price (16mb £10) i cant complain. so if u have sky TV go for it.
maybe in a years time i might look elsewhere if i have any more major problems. but fingers crossed i wont.
