I'm looking at a good drum shield for our church (I have acoustic treatment I will be using along with one). Any experiences with or opinions on any of these (probably about as much opinion on these as ? 1 - Clearsonic - http://www.clearsonic.com/lg_pic_a5-5___drums.html 2 - DrumOne - http://www.musiciansfriend.com/srs7/search/detail/base_pid/404501/sourceid=00399437396012635121 3 - DrumPerfect: http://www.drumperfect.com/Drum_Shield_Packages.asp Others? I'm considering a 5', 5-panel version, or the equivalent, but am curious about stability of hinges, and glare. Other than that, they are all about the same (1/4" plexiglass, so glare is probably the same), but prices do vary enough to make me wonder ($440 for the Clearsonic A5-5, to $289 for the DrumOne). Thanks!
