I am trying to get ahead & learn electronics. I'm just working on my general education classes now. I'm in need of a power supply. I want this to last me through my schooling & beyond. This may sound like a dumb question but are PSU's only DC out? Anyone know one that'd suit me? I'm not sure what to look (voltage/amperage). Jameco seems to have the largest selection. I'd like to keep this under $200. http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2130343_-1 I'm taking a shot in the dark. Thoughts? Thanks!
