+1 for ice maker and whiskey!
Without knowing what you have now, and what kind of work you do, it's hard to say.
I do mainly repair work, so for me what's important is good soldering gear (I have an 80's Weller WCTP, and a Hakko 936) and a decent DMM or 2 (Fluke 77 and 87-V) an esr meter, and semiconductor tester. A good variable power supply with current limiting is handy too.
Some decent cutters, locking hemostats, dental picks, precision screwdrivers (good quality don't scrimp on those)
A good stock of resistors, fuses, and low-ESR caps.
I'm re-doing my work area as well. The shelf with my scope and lab supply is too high above my desk, so plan to move it.
Also almost 1/4 of my work area is a briefcase-style toolkit, and I use about 5 tools out of it.
So hope to have some sort of holder hanging screwdrivers, cutters and other tools. That'll move my soldering stations back to the back of the desk and give me room to actually work.
I've added a Fluke 87-V and a hot-air rework station this month. Planning a possible DSO, but haven't pulled the trigger on that one yet.
