two ways to look at domain names,
first if its online search purposes only it does not mater that much, but helps with ranking if it reflects what you do.
www.anynamemakenodifferancetosearchengine.netsecond if its a name you want remembered then . co.uk or .com are easier for people to remember if it in an advert or your van.
also owning name that other want is a big business these days, i owned one that was for the allergstop network and i let it go only to be contacted by solution to be asked why i was advertising other allergy products on it.
it had been sold to a company that put an advert on it and had it up for sale to anyone for about £80 just for the domain name.
my advice to everyone is don't let any go once you have spent money on a site using it because you will be adding value to this domain name that can be sold on.
don't forget that you can add sub domain names to any domain name you own. for example if you owned carpetfitter.com you could then just add any town name to it as many times as you like
www.town1.carpetfitter.comwww.town2.carpetfitter.comand so on.....................
sub domain names will not cost you anything and provided you have the space on your server not a problem.
