Hmm, have you ever seen the film 'Indecent proposal'?
As for the straps- close, but no cigar. The GM ones are two parters- one short strap with a buckle, and it screws down at one end of the battery tray, the other stap is longer ( no buckle, just velcro ) and also screws down at the other end of the battery tray; everything I've found is just like those tekno straps that are basically a thick watch strap type deal. Scary though- I bought 4 of the 'watch straps' for £4/ $6, vs $13.99 for 3 tekno straps...
