Thanks for the offer John!
I've been doing some research and had been thinking of getting some from Scopestuff,
www.scopestuff.com/ss_flok.htm It seems to get good reviews on CN. It would cost about AU$55 to get the 24" x 47" (600mmx1200mm) piece from the US including postage. I have no idea on the cost of the Spotlight stuff for that size, are you able to advise?
Cheers
Chris
