I'm mulling over "investing" in the Retra "Ultimate Light Shaping Device" for another foray into snooting. Last time I made my own snoot with a bunch of plumbing piping - with decidedly mixed results (a subtle way of saying they were rubbish).   The online reviews I've read of the Retra LSD are all pretty good. But I'd welcome any views from the WP cognoscente.   Anyone got one they'd be interested in selling?   Thanks!   Tim
