Glass is less expensive because the materials required to build are less expensive. Keep in mind there are many types of acrylic, from High to low grades, this plays a part on other manufactures super low quotes.
Arcylic +'s:
Acrylic is clearer than starphire, it wont leak (bad seal, earthquake, or LR breaking glass), it won't need to be re-siliconed in a few yrs (you would have to remove all your live stock, lift the heavy tank, deliver it to the manufacture, then pick it up and carry it to setup again, that sucks!), it's a lot lighter to move around, and for these quote prices you better get in on this one time opportunity. I hope we can get as many members in on this group buy. Also remember PFI does not use 3/8" thin acrylic. They use 1/2" acrylic and above, plus they use better bonding solvents than the other manufactures which I wont name (found at petco and most LFS).
