I use some fairly heavy speakers for my surrounds, so I use the B-Tech brackets. Not sure these are the same model (mine are several years old) but here are some at Crutchfield (you might do better price-wise with a search).
The Btech brackets from Crutchfield are the way to go. I like 'em. They grab your speakers like a vise with rubber pad inserts for the sides. No drilling holes in your speakers is a good thing.
I use B-Tech also (my surrounds weigh 30 pounds so I needed a robust bracket) I went with the BT-1 which does require drilling into the back of the speaker. I can swivel and pan the surrounds to any position I need.
I have Polk RTi28's for my mains and 3 surrounds, and I use the B-tech BT-7 brackets on all 5 speakers because I didn't want to drill into the cabinets. The Polks only have a keyhole mount, so the BT-7 brackets were the way to go for me.
I use the HTD brackets, they are great and cheap ($16.00 ea.)! They are supporting my 35 lb. speakers (and are rated to 44 lbs.) from the ceiling and are rock solid at 70+ degrees angle.
From right to left, this picture shows my rear L-surround, and rear center surround (ignore the hanging speaker wire -- I'm working on that ):
I mounted the rear surround L/R by using the black wrought iron bracket as shown. The speaker rests on a 3/4" thick piece of pine that I cut to size, sanded, and finished with Minwax. The pine is attached to the bracket with two wood screws, and the bracket is attached to the wall with 2 molly anchors.
The rear center channel is currently mounted using a generic-looking wall-mount bracket (I'll post the brand later). I bought it at the same place I bought my speakers, and quite frankly I got ripped off. A pair cost $40, and they're made of cheap plastic. Supposedly they're rated for 10 lbs, but even using the minimum number of extensions (they can be extended for mounting to ceilings and to swivel), the plastic joints sag under the weight of the Atom.
I'm going to replace the rear bracket with a double-wide shelf that will allow me to use 2 Atoms as the rear channel rather than just 1.
Here's what Jeff Todd was referring to ... Home Depot Hardware, about $2 each package (total investment = $8.00). It did require drilling* two small holes per each speaker (x3) to mount the Heavy Duty Ring Hangers. The Picture Hangers (nailed into sheet rock) were rated 50 lbs. (the 17" x 10" x 10" - JBL S26 = 22 lbs. each)
Right Side Surround, leveled using a couple of rubber bumper squares - which helps isolates the speaker cabinet vibrations vs. the wall (hanging since Feb. 27th, 2002)
*To limit the drilling depth, I wrapped a piece of masking tape around the drill bit to mark the MAX. depth I would drill!!! Worked great in my 20' x 30' HT/family room! It's quick and solid, ... mounting speakers just like a large wall hanging!!!
Here are the stands that I will use.. really expensive but i got them as a gift... they look awesome and can support up to 100 lbs, but I got some really small take 2.2 surrounds right now. (I pland to upgrade later, way later, to some more hardcore speakers.)
