I'm in need of a tool to tighten a nut such as shown below:
Because of the tight space (area below the basin faucet), I'm never had success with the many wrenches that I used. At last, I came to know about the basin wrench which (as shown in the pic above) seem to be just what I'm looking for.
I'm from India and I cannot find this wrench anywhere in the online market (Amazon shows a couple results but they are from global store and cost a lot). I also tried a couple of local shops but they didn't seem to recognize it.
So, is there an alternative to this tool that I can get it at my place?
Some more information
These are the wrenches that I've tried and failed owing to space constraints.
