The 1.5W solar charger sold by Harbor Freight Tools works well and is

Fry's for $39.99.
1.5 watts for $13.99 is rather poor; that more than $9 a watt. More
typical prices are in the $2 to $5 per watt range. It's a buyer's market
right now for solar panels. It's not hard to find much lower prices per
watt than the normal retail suppliers are offering.
I just got a sale flyer from Electronic Goldmine that lists this one:

It is 8" x 12", and rated at 16vdc max, 200ma max, for $14.95
I got my panel for $10 from my VW dealer. It seems that VW was including
a panel in every car to keep its 12v battery charged during shipment.
The dealer was just stacking them up in the corner (and letting the
batteries die in the lot anyway). They were happy to sell me a few for
$10 each.
eBay is also crawling with small solar panels at absurd prices.
