For those of you doing mods or repairs, I've just received the 2006 MSC catalog with the new prices of poly. Their address is www.mscdirect.com. Go to quick search, type 1790, drop down a space, click the arrow, go to big book page, then click go. They have rods from 1/4" to 10" dia. and sheets up to 2" thick. I've ordered from them before, quick shipping and fair prices. Their plastic welders are kinda expensive though. Just another avenue for parts......
