Is there a cheaper alternative to this:

I don't know about the ones the OP speaks of but the Deer Creek Audio stands were made by a local artist near their place and they were constructed of 14 GA powder coated steel filled with a sandstone foam product to deaden them. 

They sounded nothing like a tuning fork when rapped by the knuckles, which didn't feel good.

All the best,

First I thought about some silly item, but realized that that is probably good and reasonable deal.

As speaker stands go that's a pretty low price and they were designed for your speakers seems like a no-brainer to me .

Whatever you get better be the same height and have the speakers at the same angle as the real stands or the speakers will not sound as they were designed to be. 

I have 2 sets from Etsy. One welded steel like these and the other solid oak. Both about half price or less. Once set up feel the base. If it vibrates a little then use some flat thin rubbery wedges, like Herbie's or even cheap ones, or you can cut them yourself. I think the metal one came with them. I also had to adjust the throw, or degrees, by either wedging just the front or rear base, to align tweeters. Depending on your throw a tiny amount of lift to front or back results in many inches of change.
