Large Spikes for Amp Stand

I am looking for a set of 4 large spikes for a DIY amp stand. I searched eBay and Part Connexion but the spikes are small 1.5". I am looking for 2 to 2.5 inches in diameter and same for height. Any suggests or links? Say $50 for 4 spikes????

Thank you.
Try these guys:
I will have a set of Audio Points 2' high with the threaded inserts avaialable.
Plumb bobs..

They are super cool looking. strong. And the top of most unscrew.. So you could find a way to screw them to a stand bottom. has 2.5" spikes.
