Since Mainstream was acquired by Confluence, which also acquired Perception, the Sound is now manufactured by Perception and is known as a Perception Sound. It is not shown on Perception's website. I just purchased a new one from Gander Mountain for 20% discount off the regular price. This kayak is a good deal at the regular price and a bargain at the discount price. There is a 3-year warranty.
At 1/3 the price (new for new) of my Hurricane Santee 116 Sport it's every bit as good, if not better in some areas. Ergonomics are very similar (cockpit opening is the same size), weight is about the same, but seat is more comfortable. There is no closed storage, but plenty of open storage under the decks for day trips. Tracks well and turns easier and is about 2 ft shorter. The Hurricane may be better on open water because of the long keel. The Sound has a tri-hull, but looks almost flat. When paddling hard, you can hear the water coming off the squarish stern. The Sound is roto-molded high-density linear polyethelene, but is sure a lot lighter (under 40 lbs) then any others I've seen. It flexes about as much as the Hurricane's Trylon, and probably won't hold up to white water kayaking. Good for slow moving rivers and small ponds and lakes.
There are no sharp edges as others have described, maybe now due to Perception manufacturing it.
