Hi Jane_C,
First of all - have you looked at moneysupermarket.com guide to broadband? It can be found here.
You'll also find a link there to low-usage and short-term deals for broadband.
My own experience is if you have broadband access at work, you'll find dial-up at home painfully slow. Many websites thesedays are optimised for broadband access and it could be very frustrating downloading that map that you imagine takes 10-15 minutes, but ends up taking twice as long.
If you're moving, you should easily be able to take the broadband with you but I think that some companies do insist that the 12/18 month contract period starts again. If you do decide to go for broadband, look closely into how easy it is to move home [and any costs incurred] before you commit.
Hope that helps...good luck.
Cheers,
