It's just kinda stupid is all. Besides, half the guaging interest threads have a price listed, so wtf?
Off topic...but doesn't the word "guaging" look funny when you type it out? Or have we all been spelling it wrong? I know my puter thinks it's spelled wrong.
EDIT:
http://www.thefreedictionary.com/gauging Here I thought they were guages not gauges in my car...? Huh...learn something new everyday.
