There is a lot of good education information on this thread. After reading all 17 pages of this thread I've learned a lot about acrylic and glass tanks that I didn't know about before. Based of what I'm seeing repeatly is that most people prefer acrylic with bigger tanks for stability and weight issues and most prefer glass with smaller tanks due to cost and less prone to scratch. This is where I stand on the topic. I am one of those that hated the look of a silicone between the glass seam on a rectangular tank. I was pretty close to getting an acrylic tank for $650 by TruVu until I found Jebo made rounded corner glass tank. I did some research online and was fortunate enough that Jebo distributor warehouse was located within 10miles from my house. I went to the warehouse and asked about purchasing direct from them and they were willing to sell to me. So here is a pic of my glass tank with rounded corners for those that have never seen a rounded corner glass tank. It's still bare because I'm not done with aquascape yet. For more pics of other Jebo tanks you can find it here.

T1, you have a great looking tank. You're so careful with your tanks that whether it's glass or acrylic I can tell your strive to keep it 110% crystal clear. Please post a picture of the top of the acrylic tank. I want to see how is this tank top brace is different from the one we get in the US. BTW, I live in the US so our choices for acrylic tanks are limited to what's available. I'm sure those better brand acrylic can be had or order in the US but not too many consumers are willing to drop $2000-$3000 US currency on a 100+ gallon setup.
Berserker, I have great respect for you to keeping your kids in check with your tank and at the fish stores. One of my pet peeve is seeing kids at aquarium stores out of control. I hate it when my nieces and nephew tap on the glass and make the fish goes berserk.
