On my 10' sit on fishing kayak, I have decided to KISS (Keep It Simple Stupid) for the simple pleasure of being out on the water, and now worrying about expensive systems either getting stolen, and falling in should I capsize. I have a painted milk crate with a lid strapped down behind me with a retractable anchor attached. I also built a PVC pipe, wheeled carry dolly that fits into the scupper holes for easy transfer over long parking lots (only weighs 5#, and stores behind my seat on while on the water).
I looked at the padal kayaks, but ended up going cheap with the Lifetime Tamarack Pro.
