routers
 

Is it worth getting one?

depends on your needs what are you looking to do?

just to get on the net?

You don't need a router if there is only one PC trying to access the net. If you have more than one machine, a router is necessary. The only advantage a router would have for you is a hardware firewall.

it's a good idea to have one in conjunction with a software firewall they work together as a good line of defense other than that you dno't really need one unless your sharing an internet connection like between an office or home network. if your worried about security get yourself ZoneAlarm thats all you really need. :thumbsup

If you need one, yeah. If you have only 1 internet connection and 1 PC, hell no! :Graucho
