Tachometer which one to buy?

[Fly1]

I,m wanting to buy a Tachometer for my bike. Like anyone I don't want to
spend a arm & leg. E-bay has cheap to $$$$$$ ones. I really would like to have
a conventicle hand dial type, but afraid the vibration on these motors would
shake the hand right off.

Before I jump off & buy one I need you guys advice AGAIN.

Thanks Fly

I just bought this digital tach/hour meter.
http://www.amazon.com/KEDSUM-Tachometer-Stroke-Outboard-Mercury/dp/B00ACDP6YU/

Just wrap one wire around the spark plug wire and ground the other.
It is settable for 2 and 4-stroke engines.

Nothing fancy but for $15 it is something I need around the shop anyway and pretty portable.
It will be here in a week or so, I'll let you know how it works.
