I now live in NYC, and my local Home Depot rents out power tools for $20-30/day. The typical tool would pay for itself in 2 days at these rates, but it's still worth it to me as these 2 days are often 2-3 years apart and I'd rather not store these tools in my cramped 1BR.
What I would love is a community-run tool rental service where we can donate a tool + pay a nominal membership fee, and borrow tools for free. I am happy to donate a $120 circular saw/impact driver if I can rent 10x different tools once each for $5/mo for the next year. The closest thing I have now is my local hackerspace, which is great, but I often have to work on my projects at the space, which limits the kind of home DIY I can do.
