Power supply question

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?

Start with circuits of potential amps you want to make. Figure out the power needs, the current loads, and the voltage requirements. Overestimate and then look for PSU's that'll fill those needs.

For a general purpose supply for projects, you might want to consider getting a 2- or 3-output supply. For many circiuts (especially when using opamps), you will want a split supply like +/-12V. A 3-output supplly with +/-12V and +5V outputs is very useful.

On the other hand, if you are looking to build some audio power amps, then the supplies you are looking at fit well.
