Ultrasound Technician

Do you feel that it is very cool to be an ultrasound technician ? May be some of you will laugh at my question , but I think it is really a nice job. But from what I know ,there is not easy to get this job. We must study at ultrasound schools or sonography schools first , and then get the certificate that we are really can do this job. I see they also have a bit of long hours if they are in hospital , but the salary is nice too.
