Our phlebotomists at the hospital make between 17-21$/hr I think, as a rad tech I make 32$ (being part time I also get 12% in lieu of benefits, and 6% vacation so I actually make closer to 40$/hr) U/S techs make a bit more, but often suffer more shoulder and wrist injuries.

For us, phlebotomists only draw the blood so the course is only 16 weeks or something like that. The lab techs that run all the testing have longer at school and get paid what I do.
