Rick, that is the difference between California and SW Indiana. For certain things, we are in a wasteland. I'm not saying it doesn't exist...but it wasn't worth me super-sleuthing it. In my life, time is the only resource that is truly scarce. I did look at Home Depot while I was there today burning a hole in my pocket, but just for aquarium top material. Even their really thin, flimsy, cheap crap isn't cheap.
All of my pieces are at least 12x15 anyway, so I will make myself feel better by rationalizing pieces of that size wouldn't be in a scrap bin anyway.
As far as cutting, I've got a table saw with a nice Diablo blade for acrylic (80 tooth, zero rake angle).
I also have a router, table, and spiral bit for acrylic.
I picked up my lumber for my QT tank racks too. The next week is going to be a building frenzy.
