My location monitors used to be the K+H O110D.
I upgraded last year to the Geithain RL906
(PDF of the SOS review is HERE
The other good pair is the Neumann KH120A
(which are the replacement for the old K+H O110).
As these are ideal location monitors, both Geithain and Neumann do a flight case and padded carrying bag option for these monitors (the Geithain is UK made but available to all Geithain dealers worldwide) so that they can be taken on location without fear of damage. Geithain also do a carrying bag for the optional table stand for the RL906.
