I purchased a 40 breeder about a year ago and built a stand for it, but I scratched the glass when I was removing the sand that was in there initially and it was driving me nuts, so I bought a new tank last month during Petco's famous $1/gallon sale.
I was also able to score a really good deal on some Eco Complete using a coupon code I had gotten in an email paired up with an online sale -- had 5 bags delivered to my door with 2 day shipping for about $60.

Here's the abbreviated stand build...
Initial set-up w/ old tank...
And here it is now after I set up the new tank, still very much a work in progress -- right now it's just a bunch of needle leaf and anubias nana with a dwarf sag foreground, there's also a Crinum calamistratum and a few small Hygrophila pinnatifida in there...
I am waiting on some more anubias nana to fill in the left side and I need to figure out what to do with the hygro and crinum, if they do stay in there, they definitely won't be where they are now, but I'm leaning towards putting the hygro in another tank.
Once last pic, this is the Serrasalmus compressus that calls the tank home...
