Get whatever clicker wrench suits your fancy (and with markings that you can easily read) and also get a simple beam-type to use for calibration checks. The clickers will change calibration with age (spring seating, temp, pivot wear, etc) while the beam type will never loose calibration as long as the main shaft doesn't rust.

I clamp my clicker (whichever one I'm gonna use at the time as I have five of them) into my bench vice and set it to a value, say 75 Ft-Lbs. Then check it with the beam type to see what value it really snaps at. Then adjust the clicker to get the desired setting.

I have several ranges of clickers: 30-250 In-Lbs (low range), 15-100 Ft-Lbs (low-mid-range), 10-150/30-150 Ft-Lbs (mid-high range) and 50-300 Ft-Lbs (high range). Note that things like lug nuts aren't very critical while things like spark plugs and head bolts are more so.

Beam-type 10-100 wrenches are about $25/US and 20-150 clickers are in the $50-100/US range. With both of those you can easily check 30/60/90 settings between the two.
