Thanks for all the replies.
I'll definitely go for the NIC option - I've got broadband myself and I've always used an NIC. I never bother with the BB installation CD either. I've got loads of spare cards floating around so that won't be a problem.
I'll give CS a call tomorrow - I just thought I'd post on here first cos I know CS have been having huge technical problems with their computer system over the past couple of days.
Thanks again
