Help with choosing bike to bike comms?

[weirdfish]

As the title suggests I need help locating a half decent but cheapish bike to bike comms set, mainly to be used to give some instruction to my step son who has just bought a 125 Varedero. Any ideas guys?
Thanks
Jim
p.s. I saw Molestranglers original post dated 2007and checked out the website he recomended but unfortunately the set he was on about is no longer stocked.

sorry I may be a bit late here but we've got cobra 600s which we bought here: www.biketobike.co.uk/
They were pretty cheap and work quite well - the vox is a bit slow to respond but you get used to it.
