I'll add too, most specialised tools these days can be found for cheap, while everyday tools are worth investing in quality once rather than renting every weekend, so I've never felt the need. A torque multiplier though, I've looked, and I just can't find the right kind of one for cheap - there doesn't seem to be a Chinese knock off I can buy, and there doesn't seem to be a secondhand market. Crazy for something that's just a few gears in a case. I got a 5t block and tackle built like a tank and older than me for $40, but I can't find a torque multiplier for less than $500.
