I didn't spend anything on the wood for the 10 gallon tank stand, because it was all leftovers from the other stand. For the other stand it was 2 sheets of oak veneered 3/4 plywood - about $80, plus about 5 - 8 foot oak 1 x 4's and 1- 8 foot oak 1 x 6, which were about $60-70. I had scrap 3/4 plywood on hand for the top, bottom and back, so those didn't cost anything. All of that is from memory. Wood is no longer a cheap material.
