A sensor on a fingertip is probably not such a good idea for a rower.  I
have used a pulsemeter with a sensor clipped to the earlobe.  I'm afraid
I don't own one, but I know that at least one retail outlet for Schwynn
Air-Dyne(tm) exercise bikes (highly recommended, by the way, but costly)
offered them as a "sweetner" along with the bikes.  As a freebie with a
bike of that price, I'd guestimate the list price at 30-60 dollars.
The pulsemeter seemed to work adequately.

As a handy tip about ear-mounted optical pulse sensors: beware of strong
fluctuating light sources.  I know of someone who got *very* anomalous
readings due to excersizing where alternating shadow and sunlight fell
on the ear with the sensor.  Shading the excersize area solved the
problem.
