Hi Keekers,
I know what you mean. Glass and pyrex tanks are not cheap. There are delrin tank tubes available at low prices. Being delrin, it means that seeing your juice is not that easy. The colours are limited (black, white and red) but because they are chemically inert, your juice will be okay.
Finding these on the internet is not easy so I will post links to some images.

You can always jazz them up with some decals, but it is definitely a victory of practicality over looks. Maybe get one of these while saving the money for a pyrex tank?
Love to All,
