Wow Buk, you got a good deal, out here GE Polymer wont sell tubing cut so you have to buy the whole length. I paid about $60 for 6 feet of 4 inch extruded. They (GE polymer) also told me that you can't get clear acrylic in any size larger than 4 inch and stay with extruded, over 4 inches is always Cast (waaayyy more expensive) but I've found out that rep was wrong, you can get it as extruded.

For the record, Weldon 16 worked well for me, I've got a cheap little wobbly table saw so I guess my cuts weren't all that pretty. A 4in hole saw cut the end peices to the right size for that acrylic tube to slip right in.
