BT, get £20.. to join!!
I know everyone says BT rips us off, but have had excellent service and connection with them at full band width, how did we all cope before!!., I remember when we got our first Fax machine on board ship back in 87, it was like black magic!!, and the first mobile, where six of us at a meeting, filled the table with our "Bricks".
Anyway back to broadband, go wireless at the the off, if you have more than one computer and kids, it also gives you a second line, handy when you or the Kids are on line all the time.
i got a Voyager 2000 with aUSB card and connect my laptop directly with the cable in the office but can go outside in the summer to work when I want and the lad uses his anywhere as well, don't see any differnce most of the time when we're both on line.
If you are a mastercard holder or if you go to MSn I think you can get a further discount, phone BT and say you can get a better deal they were helpful with me, they all want the sale.
Wireless is expensive to start with, but you'll end up there in the end so you might as well go there to start with.
best of luck.
