I use a Itechworld ULTIMATE SOLAR GENERATOR KIT - ITECH1300P, 200W SOLAR BLANKET & SOLAR ADAPTER, not cheap at $2,832 (for the lot) but has met my expectations and works great...
Keep an eye on this site, it is where dometic sell their factory seconds.
I have bought from here a number of times, cheaper and so far it is only the carton that was slightly damaged.
