Building with acrylic isn't as difficult as it looks. I did some reading and found some really good/helpful sites related specifically to acrylic aquarium construction.
This thread
here that CraigC of Gems of the Rainforest started was very helpful in directing me to good info sites.

were also very helpful reads.
I built this one cage for a little over $150, but I bought about $60 or more in startup supplies, such as Weld-On #4 (solvent cement for acrylic), a couple framing clamps, etc. I simply score cut the 1/4" acrlyic and snapped it at the score lines and then cleaned up the joint edges with a router table. I wish I had the table saw and the right blade because it was not a quick process to score cut that many pieces. It took many hours to just simply get the pieces rough cut before they went to be routered. I believe that a table saw with the right blade may make good enough edges to skip the router step as well. After that, assembly is almost a breeze if you've got help. You set it up dry and syringe the cement into the gaps of the joint. The cement is water-thin so capillary action draws it into the joint and then it is clamped tight to dry. The cement sets in seconds and is very strong in under 5 minutes, so you'd better have it in the right place when the cement is applied.
