I am just wondering after reading all the posts, how common are acrylic tanks in the USA? Up here in Canada they seem to be fairly rare. I honestly can not recall ever seeing one for sale in a LFS. I wonder though as they seem fairly common in the US. I can see many advantages to the acrylic and I guess I really am just curious as to how common they are in the US. That is it not a real big deal just a question.
