I found this supplier while looking for aluminum rings to use on tree huggers. They warranty the rings to 250 lbs but they say a single ring will lift 3000 lbs. Maybe someone has the ability to do some testing on them but if they work, they are sold in pairs so at $3.30 / pr compared to around $3 for a single.
Where did you see the 3000 lbs rating? I only see 250lbs on the website.
They are available in different colors, which is kinda cool.
It's on another page here
It's totally un-official and when questioned about it they always come back to it's only guaranteed to 250 so it may be a fluke or maybe they just don't want people going out and trying to climb mountains with these.
Why chance it, here's 50 grams, 24 kilonewtons holding power, or 5,400 pounds, at REI for $4.93 each. http://www.rei.com/outlet/product/760354 I'd spend the additional $1.63 and not worry about it. Plus if you have them delivered to a store by you, there's no shipping charges. If your not a member of the co-op, let me know and I'll let you use my co-op number. Won't help on your purchase but I'll get credit that way.:)
Check it out
Other than the color options :) the main reason would be cost (I'm a cheap-scate).
You'd spend $20 + gas to go pick them up (so let's round that to $30) at REI. These rings will run $10 delivered. That's worth the test to me to save 10 - 20 dollars.
Aye, a true Scotsman, through and through. :)

A cuckold, coward loun is he!
Wha first beside his chair shall fa',

If you are a true Scot then you will really love the SMC descending rings.
You can buy directly from SMC for $2.75 each.
You don't have to be concerned about the 250 lb limit since the SMC descending rings are rated to 3,147 lbf - 14kN.
So be a True Scot and get the cheaper and stronger alternative.
Ay, but a True Scot will nae pay $2.75 each when he can get the same thing for $2.10.
