Ok guys I plan to install a tachometer sometime in the future. I want a way to calibrate it other than a wide open throttle blast. I have been watching various brands and prices in hand held digital tachs. All of the instructions are about the same. Put a reflective strip or a white painted mark on the balancer and scan the mark with the beam from the hand held unit. Anyone already have one of these? Most of the ones I have seen advertised are usually in the $80-125 price range. Today this one shows up in my email from a company in CA that I buy my computer related parts from:

What are your thoughts and opinions on this? This wouldn't need to be a rugged tool that gets used every day but does need to be accurate.
