Frank Harbor freight has a very good deal going on right now. You can get 3 15 watt panels a controller and a light for 199 bucks that's about 4.50 a watt which is good especially with the controller. I've already bought a couple for use with my greenhouse. Just though I'd pass that on. As far as motors C&H sales has a good selection of dc gear motors at reasonable prices. Several here have bought the 39.99 gast compressor from them that I passed on just type in gear motor on the page and you will see all kinds. Just some ideas.
