In regards Slink.
A review recently appeared at the Online-Visions website. They state a source (Wal-Mart) for the rings in the US at $5.95.
We had considered supplying the rings with the booklet, but that would have forced a retail price of about $29.95, at least. (Margins are magnified through the manufacturer/jobber/wholesaler/retailer - customer chain).
This plus a couple of other reasons prompted us to omit the ring, thus keeping the low price point.
An advantage is that you can start with a cheap ring while learning the moves. If you find that you want to add it to your pro material, you can locate a nicer set. If on the other hand, it does not pan out, you have not wasted a lot of money.
The Visions address (for the Slink review) is www.online-visions.com/reviews/index.html
Hope this helps.
