finally got one...........
they are brilliant........ had it fastened to the tower and we got some great shots of the grand children and our kids on their boards........
problem I had was getting a decent case for the thing...........
for all the MC owners down under in Australia or even in the US I guess......, I got my case from these guys..........
I got the SP case - small one - it is perfect and came quick.........
