Here's what I ended up with. It's a mixture of mostly Craftsman, Channel Lock, Stanley, and Harbor Freight, and it came in right at $200 if I ignore the sales tax. (I kind of blew the budget a little with the fancy Estwing hammer and that box-end wrench)
10" Channel Locks
1/2 x 9/16" long-beam box end wrench
22" plastic toolbox
Folding utility knife
10" hacksaw
12 oz claw hammer
electrical outlet tester
tie wraps, 4" and 8"
wire strippers
3/8" socket set with ratchet
22 pc Metric and SAE combination wrench set
8 pc heavy duty screwdriver set
Metric and SAE hex key sets
4 pc 3/8" drive extension set
8" needle-nose pliers
6" slip joint pliers
4 pc pick and hook set
3 1/2" nine LED flashlight
43 pc ratcheting T-handle 1/4" driver set
2" putty knife
15" wrecking bar
4 pc tiny screwdriver set
pocket reversible screwdriver
16' metal-cased tape measure
nailset punches (3)
8" torpedo level
bottle and paint can opener
Everything except the T-handle driver set (which has its own nice hard case) just barely fits in the 22" tool box. It'll be a PITA every time she needs to get something out that's not right on top. I told her she could take the hammer and pry bar out, then put the sockets in ziplock bags, and everything would fit better but she likes having everything in one place and in the smallest box that will hold it.
