I need to buy a calibrator for my desktop Mac

[Angelblade131]

I have a 27-inch 2017 desktop iMac.  I really need to calibrate and now have the money to buy one.  Is there a certain one I should get based on the computer I have?

You're lucky.  Every calibrator on the market will run on that computer.

Get the best one you can afford.

I'd recommend the Calibrite Display Pro HL (CCDIS3HL). As Damien pointed out, it will work fine with your current 2017 iMac, and will work fine with the new Apple Displays if you decide to upgrade to a new Mac.

When I upgrade my 2017 27" iMac, that's the Calibrator that I'm personally buying.

Where can I find the instructions to start calibration?
