Your complaint on price seems to show you are unaware of a manufacturing idiom called "economies of scale."

I have a three mobile wireless dongle/modem
i want to be able to share it, i have found you can buy wireless routers to do this, but they seem to be £60+ because they also contain a mobile receiver transmitter
my question is, is there a wireless router, that accepts a usb dongle for the modem connection rather than containing the mobile equipment? which makes it so much more expensive, as the dongle already contains the mobile part anyway
