James - i'm not sure if you will be happy with glass cages.
With them .. you def. get what you pay for ... their silicone work is very bad, their trim is flimsy, might as well not put it on.
A friend (local) picked one up ... his silicone work is worse than AGA/Oceanic.... way worse.
Their tanks are also built like a tank ... for the bottom they use double panes of 1/2" glass .. an 8 foot tank will weight somewhere around 500-700lbs depending on width & height.
When he picked his tank up - he didn't notice right away as it was covered up - but his tank has a fish eye on a corner, and a scratch on it.
Just to mention - most of their work seems to be done in a shed in the backyard - by nothing but imigrants that don't speak much english ... when my friend picked up his tank ... they had a bunch of dogs jumping up on his truck as well ... scratched his truck up.
Do a little research on Glass Cages, and you will find very mixed review - some have had no issues at all - others have nothing great to say abou them.

3. Grows Coraline easier (CON)

There are many pros & cons for each ... i like the acrylic .. but recently switched to glass. I like the easy of cleaning for the glass ... don't have to pay as mucha ttention ... but i kow i will regret it one day once i scratch the glass... as i will not be able to remove the scratches.
