Seems ok to me

Guidant is under fire for paying doctors $100 to fill out a survey providing their feedback on defibrillators and pacemakers. I haven't seen the survey but if it's asking legitimate questions that Guidant needs answers to in order to develop products then it seems reasonable to pay doctors for their time.

One aspect of the survey program does seem a little suspect, though. Apparently doctors are allowed to fill out multiple surveys.
