Having done the same long ago and gone through both wired and wireless solutuions I would strongly recommend you go wireless. Get a wireless router with a built in firewall and wireless networks cards in your PCs. It is unbelievable easy and no hastle about sharing your internet connection using a PC with a software firewall. DON'T leave a PC directly connected without a firewall. It took me 4 hours to sort out the viruses and trojans my brother in laws' PC after he did!

PC world, although often not the cheapest, do sometimes do a good package deal including a wireless router and a couple of cards. 3Com/US Robotics seem to be about best at the moment with 54Mbps ready for 100Mbps. Check it out and you might be surprised. (You are UK aren't you?). Incidentaly who are you going with? I am getting a bit cheesed off with NTL and thinking of moving.
