New purchases for your plane from OSH ?

Lets see, where to start.
First day, bought a set of rivet squeezers,
next day the tool to drill holes in the heads and
threads of bolts, gloves, extended drill bits, 1/4"
socket extensions, a few more items that pass my
memory. Day 3 I went around to all the headset salesman
and tried each a couple of times. I'm on a budget so the $900
Bose was out of the question (although I tried them). Ended
up with an inexpensive set of PCA anr headsets made by lightspeed.
