[newbie again! a few questions]

I am again getting into electronics( I took a course in highschool 14 yrs ago)
I will mainly be doing projects that have to do with audio ie amplifiers and effects, but also have a interest in radio and computers.

I want to get a breadboard and power supply to start experimenting. Cheap is good but I dont want crap.

I am looking at this for a power supply. I will most likely dealing with circuits that need less current (300-600mA) Will I still be able to use this?

would this be better?

and this for a breadboard. I assume I can hook this up with the above power supply?

I am just getting started reading an electronics theory book that has experiments at the end of each section.

are these two piece a good start?
are there better for the money?
can i use a regular power supply like this somehow?
