You might want to try a PM to Joel Weiss here on the Beaver site, as he lists in his post closing as being the "WiFiRanger Ambassador". From the investigation that I did on both of those products last year, to me, they both looked like winners, but still a bit pricy.
I have an old Jefatech wifi extender (circa 2007) which still works, but is somewhat a hacker's chore to set up at each CG..
