where is the best place to install tachometer???

Hi everyone, Ihave 2001 k11 micra and I want to install tachometer but i don't khow where is the best place to source one from?
Any suggestion? Thanks for support!
Got mine off eBay but it's pretty slow and dim-witted, I'd say avoid cheap ones and buy a brand name one if you're able to, Autogage, Bosch etc.
There are plenty of sites that sell them in all sizes. There are some good Autogage ones on Amazon.
