Make that plural - power supplies.
You can never have too many power supplies. External ones are better.
Make sure you get one at least one with adjustable current limiting,
makes it harder to blow stuff up! :->
+/-0 to 15V @ 1A adjustable, and several fixed voltages (+5V 2A, +12V
2A) are the minimum you'll need.

Get one that measures capacitors. Inductance can be handy too.

Second hand on eBay is the best option.
A 20MHz dual channel analog is a basic requirement, although 50-100MHz
ones can be had cheaply too, some people even throw them out. If you
ask nicely on the groups telling them what a keen beginner you are you
might get one for nothing! ;-)

Remember that you won't be able to view a 20MHz square wave on a 20MHz
scope!

Add a function generator (sine/square/triange to say 2MHz).
A logic probe if you work a lot with digital stuff.

You basically need the ability to generate signals, view signals,
measure stuff, and power stuff. That is covered with those 4 basic
instruments mentioned.

On the component side, get lots of "kits" and "grab bags" that have 10
or 100 of every value.
