Extensive research on small solar systems <5 watts led me to this little inexpensive ($12.99) charger from harbor freight. Sure it is big, but it is also 12V at 1.5 watts and cost less than some 1 watt panels when shipping is included (http://adafruit.com/products/262). it is a 22.25V open circuit but who wants that awkward voltage? 12V is a nice round number so i kept the trickle circuit and stepdown in.
I took apart the car charger part and did my own little edits to it and made it into a nice little solar source.
