Take a look at Fol-Boat's K-Pak folding kit. It's a 9' foldable kayak, aluminum frame, waterproof skin, sets up in 10 minutes (no compressor required), weighs 21 pounds and fits in a backpack style storage pack. It comes with a 3 year warranty, (our fol-boat is now 30 years old and still floats, although I do need to order some replacement fabric that's leaking near the original folds).
Price is around $900 each, but right now there's a $300 off sale at the factory.

Sea Eagle and a few other companies do offer "inflatable" kayaks, the main problem I see with them is the requirement to inflate, which means a "high volume compressor" and there's always that "stick or sharp rock" that causes a leak. For us, patches NEVER seem to work permanently. YMMV
