I am an EE student and would like to get my own power supply so I can experiment at home. I saw these two power supplies at frys and was wondering if they are any good. One is 0-30V 0-3A and the other is 0-60v 0-1.5A. I would like to experiment with making audio amplifiers. Which one of these would be a better choice? Or, do you have any other suggestions? http://www.frys.com/product/1693249?site=sr:SEARCH:MAIN_RSLT_PG" http://www.frys.com/product/1693238?site=sr:SEARCH:MAIN_RSLT_PG"
