Ok, I'll bite....

Many soldering stations that are temperature controlled, plus lots of 
spare tips and replacement parts.  A larger number of inexpensive (as 
long as they have quality temperature control) spares are probably 
better than just a couple high-end units.

LOTS of extra tips, sponges and other soldering iron parts.

Hot air station and preheater, for specialty soldering.  I use Aoyue 
852A & 853A and they work fine and aren't terribly expensive.

A vacuum desoldering station might also be worth considering.

Microscope on boom stand, plus a good ring light.  This is expensive but 
critical for soldering tiny SMT parts.... assuming you want to support that.

Desk lamps, probably some with the magnifying lens.

Solder, wick and flux.  If you stock a water soluble flux (superior for 
tiny SMT soldering), you must have a sink to wash the boards and a small 
low-temperature over to bake them dry.

Multimeters, digital with auto-ranging.  Spare fuses!

DC power supplies with good quality current limiting.  Current limiting 
makes the difference between "whew, that was close" and a burnt-up board.

Hand tools:
Tweezers
diagonal cutters
wire cutter/strippers
crimping tools
needle nose pliers
small screwdrivers
IDC connector press
PLCC chip extractor

Clip leads:
alligator clips
pamona mini-grabber types (my favorite)
clip-onto-chip types

power outlets everywhere (I bolted 2 of the wire mold types with an 
outlet every few inches under my desk, one on the front and one on the 
back...)

Basic function generator

Probably an oscilloscope

breadboards


I personally don't etch boards anymore... but a good number of people 
are interested in that.  I'm not going to list stuff for etching your 
own PCBs.



Possible consumables:

Wire rack with lots of wire....
#30 solid for wire wrap and point-to-point prototyping
#22 solid for breadboard connection
#24 and #18 for general purpose wiring
ribbon cable
maybe some shielded multi-conductor cable
"magnet" wire, maybe #24 size

pad-per-hole prototyping "vector" board

Resistors: 1/4 through hold and 0805 SMT
1, 4.7, 10, 22, 51, 75, 100, 150, 220, 330, 470, 680, 1K, 1.5k, 2.2K, 
3.3K, 4.7K, 6.8K, 10K, 15K, 22K, 33K, 47K, 68K, 100K, 220K and 1M
assortment of trim pots

Capacitors:
10pF, 22pF, 33pF, 100pF, 470pF (NPO types)
1nF, 2.2nF, 4.7nF, 10nF, 0.1uF, 1uF and 4.7uF (X7R types)
10uF, 100uF, larger? (aluminum electrolytic).

Transistors:
2N3904 & 2N3906
TIP120
IRF640

Connectors:
Single and dual row headers
IDC sockets
DB9 and DB25, solder cup + hoods and also PCB mount types
DC power jack and socket (5.5mm barrel, 2.1mm pin)
1/8 inch headphone jacks and sockets

Voltage regulators:
7805, 7905, 7812, 7912, LM317, LM337
LP2950-3.3

various microcontrollers (probably AVR, maybe PIC, maybe maybe TMS430)

IC sockets

SMT-to-DIP adaptor boards

Digital logic chips
74HC00, 74HC02, 74HC08, 74HC20, 74HC138
74HC04, 74AC14, 74HC125, 74AC245
74HC595, 74HC4094

Analog chips
LM358A
LM324A
LM339
LM336-2.5
NE5532

8, 14.7456, 16, 18.432, 20 MHz, etc

Hardware:
4-40 screws, 1/4, 1/2, 1 inch + 4-40 nuts and washers
4-40 threaded standoffs

Switches:
momentary pushbuttons
slide/toggle switches

LEDs in various colors, sizes
