Ebay has loads, most better and cheaper than Argos.
I have used some with ranges up to 1km with colour and sound, and
depending on the terrain and other interference they seem more than
adequate, especially for CCTV.
Closer in I haven't had much hassle.
Currently use on the rear of my van as a reversing aid
I think that you will find that those "with ranges up to 1km" from ebay
are not legal to use in the UK.

Whether that bothers you or not is up to you but if everyone used such
high powered devices there would be a need for even higher power (and so
on) as these devices would, inevitably, interfere with each other over a
greater range.

This is one case where more power is not better.

1 The OP didn't mention if he wanted a legal version
2 I have yet to see a published case of prosecution for using a device.
3 DILLIGAF if it's legal or not if it interferes, given that there are
*so* many other devices interfering with transmissions in this world
