Highly recommend doing a search on Amazon - they carry a bunch and customer reviews can be illuminating and some are quite detailed by knowledgable users.

I bought a Midland from Amazon a couple years ago that I still need to have installed.

Somehow slips my mind when I visit my mechanic. I might just add that to the to-do list for my next oil change. Has to be hidden in my car so will see what they suggest for that.
