I used to put my Quad ESLs (aka "57"s) on cinder blocks. Perfect height and you can paint them any color you like. If you have a hammer drill and masonry bit you can fit them with spikes too.
After that, I bought some solid 1" x 1" square steel and had it welded into some custom stands by a local welder working out of his garage. The problem is that paying for steel and cutting, welders, paint,... it all adds up and it was just a little more expensive to buy the audiophile stands.
Another option is to buy 8" concrete form tubes at your local Home Depot, cut them to the height you want, tape off the bottom really well with plastic, fill them with quickcrete and set your steel spikes sticking out of the top (which will be the bottom). This would be a more acoustically diffusive shape and would not create much diffraction from the speakers. You can wrap them in fabric or carpet, paint them, or whatever you like.
If you can get your stands used I think that's the best value out there.
