I have a pair of these and they work well. also use a tether as well to be sure. You can buy replacement bits if required. http://www.mroptical.com.au/9-1-009.asp?pvar=584 Says they are not taking orders at the moment tho
If you see your local gp Tell him you feel inadequate in the bedroom there might be a chance you can get a strap on, then use the sunnies to disguise yourself when collecting prescription
I second Silverfish have bought a few pairs usually arrive within a week...last pair were quicker from the states to Australia than they were from Melbourne to Torquay
