I would like your thoughts on the following dilemna. I am developing a site for a friend who has registered 3 versions of a name. thename.com is already taken by another individual selling similar but not identical products in the USA. It has not been registered as a company or copyrighted.

Our site will have a shopping cart and supply the UK only. We have registered:
the-name.co.uk, the-name.com, thename.co.uk (thename not being the real name)
Which name should we consider using? We are reluctant to use another name, as it does reflect the product and my friend has used it for some years to mail out goods in the UK.
Your thoughts and ideas would be appreciated
Maia
