yes I mean build my own. I've seen people's projects but no actual blueprints for them.If you mean build your own, I've seen plenty of DIY projects around the internet. Just google it.
But if you just want a cheap stand I would go to a thrift store and buy a dresser or sturdy desk. I've got one 10 gal on a chest of drawers and other on an old wooden desk. Pet stores will have them, but they are often between $70 - $100.
