Sorry for bumping such an old thread but this discussion has popped up in my Google Search Results dozens of times when searching for random medical-physics related terms, for whatever reason.
Thought I would throw in my two cents.
I studied medical physics at the University of Kentucky in Lexington, KY. Kentucky has a very long-standing CAMPEP-accredited radiation oncology oriented medical physics Master of Science program that requires two years to complete.
As far as opportunities for clinical experience go I consider UK to be an excellent option. Technology-wise, UK has 5 Varian linear accelerators spread across the main campus (2) and the three satellite facilities (1 each). There is an active TomoTherapy program as well as a Gamma Knife program at the main campus. There is a very busy HDR and LDR brachytherapy program (gynecological, prostate and other interesting sites and techniques). There is a samarium program. UK is active in IGRT, IMRT, SRS, SBRT and in research (though the program is very much clinically focused you will be required to do research).
Throughout the program the students will get hands on experience in all aspects of machine quality assurance including annual calibrations. They will complete a lengthy treatment planning rotation that includes everything from basic hand calculations to IMRT. They will be involved in brachytherapy treatment planning and quality assurance. They will also be involved in patient-specific quality assurance such as IMRT QA, TomoTherapy DQA, weekly chart reviews, treatment plan reviews, in vivo dosimetry, etc..
When I say the students will be "involved" in these things, I mean that they will physically be the ones doing them. They check the charts themselves. They check the treatment plans themselves, they perform QA themselves, they do treatment planning for actual patients being treated, etc.. Of course this is all done under the very close supervision of faculty physicists.
As far as preparation for the "real world" goes, I can give my experiences. I interviewed for only two jobs before being hired (though I applied to several more). During the interviews I was able to intelligently discuss the field and my responsibilities and I was able to make it obvious that I had plenty of hands on experience (for a new graduate, that is). I left graduate school with a "Clinical Experience and Skills" section on my resume that I was very proud to present to potential employers. I almost never had to answer the question "What experience do you have regarding ____?" with "Well, I've really only read about ____."
I ended up finding a fantastic, high-paying clinical physics position in a very busy radiation oncology department program that has an active brachytherapy, external beam (including IMRT) and TomoTherapy program. I was able to move into the clinic as a new employee and within my first week was was able to significantly contribute to the productivity of the physics team (which was shorthanded beforehand). The group here is very happy with their selection to hire me and I feel confident and comfortable in the clinic, which is important.
Having only been through my own graduate program in medical physics I won't try to make comparisons with other programs, but I will say that UK has a long history of producing excellent CLINICAL physicists who go on to have very successful careers. Just wanted to throw that out there because as a school, UK certainly doesn't have the reputation of Harvard or Stanford or MD Anderson, but as far as clinical medical physics is concerned I feel that it deserves some recognition.
