I would say do it yourself
you will have alot of fun, and it would be alot cheaper. I made mine for under 30 for a 75 gal. aquarium and made a stand for about 10. I am now in the process of enclosing the stand for our baby. Got the glass in the back, tile on the floor. It will end up costing about 35 for the bottom because I had to buy some channel, and vents for the sides, but it's alot cheaper then buying one. All I have used throughout the process is a Jig Saw or scroll saw whatever you wish to call it lol and a drill, razor knife so not much equipment to buy, other then that a hammer and screwdriver lol...
