Besides the necessary hand tools and the parts bin with various ribbon cables, switches, enclosures, spare chips, screws, etc, I've a Hakko 936 soldering station, Radio Shack bulb desoldering iron, Edsyn solder-sucker (two models), no-name chinese multi-meter (looking for a deal on a good RMS meter currently). Just recently, I picked up a Gordak 952 SMD rework station which includes a soldering iron and uses Hakko tips and elements (of which I've a plethora of tips). Looking forward to being able to do a bit of SMD stuff - though obviously I've some practice ahead of me (and still need to practice more with the regular iron!)
Assuming that my skills come along, I'd like to eventually add an o-scope, bench power supply, and logic probe. Eventually. I've a long way to go before I can even begin to put those to use.
