I am looking for the best mech keyboard for under 150$ go!

Do you need an extended bar of hotkeys?

Ask this user about mech boards she/he owns the most n the site I think and has tested the most.

Also what features are you after?

Back Lighting
Macro keys
Disable windows button toggle
Compaq/Full size
Numeric Pad
etc

Do you have a preference on keys?
If Not then look into them by going to local shop and testing each out.
They all respond differently, some like browns some like blues etc.

I would like a full size keyboard with the number pad and back lit preferably red but not picky. And I would like macro keys but those are not THAT important.

What kind of cherry switches you are looking for ?

Brown red or blue
