[dorkbotsea-blabber] Small section of large-diameter acrylic tube wanted. Where to get?

Howdy.

I'm looking for a short length (~2') of 18" or greater diameter clear acrylic tube with a minimum thickness of 1/2", 1" being preferred.  This stuff is impossibly expensive from places like Laird.  Seems unlikely but I may as well ask:  Anybody know of anyone using copious quantities of this stuff who might have some "scraps".  Or otherwise any place that might be cheaper?

Very best,
Aaron
