I have definitely fallen into that category and have some of those crazy tools with very limited usage, including the tool to pop out the pivot balls on a 12th scale and the LED kit for locating body post holes in painted bodies. I have a lot of the bulky stuff too including tire truers, tire sanders, tire warmers, etc. Honestly though, the right tool for the right job makes things sooo much easier. It is a slippery slope though.

Buying quality at the start always matters though. Saves you a ton of headaches down the road when wrenched break or screws strip out.

I even carry a 3mm helicoil kit with me for spot repairs for myself and track buddies when needed. Nothing like salvaging that bulkhead or steering knuckle when the hobby shop is out and you still have a race left.
