Gary,
I have been trying to find someone locally who gets there Microfocusers in.

Sold by Starizona in the US. Edit: seem to be the only ones other than OPTcorp that list this, also they have the best price on special right now.

For some reason they are not listed on the website you linked. Are you able to get these.
Regards
Fahim
