Personally I own
Duratrax ultimate car wrench [link=http://www3.towerhobbies.com/cgi-bin/WTI0001P?I=LXTC89&P=8]http://www3.towerhobbies.com/cgi-bin/WTI0001P?I=LXTC89&P=8[/link] it also has a excellent glow plug remover seeing the end holds onto the plug. I own another plug remover but its a piece of trash compared to the duratrax one.

I also have a $10 screwdriver with 10 bits from the home depot, a pair of needle nose pliers, a set of hex keys, a cheap small flat head screw driver(for tuning), and 1 longer craftsman #1 phillips screwdriver (I only need it for my savage)

I've not run into anything I can't work on yet with my trucks.
