Alternatives to Stillpoints


I am using the Stillpoints Ultra SS with good success in some of my gear. Looking to complete two more sets. Then it hit me, is there anything better (preferably cheaper) out there?

I owned stillpoints with risers, an old version. I replaced them with Machina Dynamica Springs, which control vibrations in 3 dimensions and relatively speaking, cheap
Yes @yoby I do use wooden shelves and rack. But those are not your warehouse woods. My rack is made of 4” and 2” thick air dried solid maple wood from Mapleshade:

They are excellent. So may I suggest you take a look before you put them down?
I actually make a dual layer mass on spring iso stand, the Nirvana, Revelation Audio has one, it’s two stacked layers of heavy masses on springs. The trick is keeping the resonance frequency of each mass on spring layer far enough apart to avoid any untoward interaction. It’s how the big boys do it.
@ thyname, I own a 2 inch  maple shelf from Mapleshade as well, and have done extensive comparisons of different shelves over the years ( Mapleshade,  Adona, and Marigo Audio)  I meant no offense to you and apologize if I did. 
Pop quiz,

Why is a 4” maple board better than a 1” or 2” board for isolation?
