Maybe some graduate-level classes need to be taught by a researcher in the field and so students will simply have to deal with any deficiencies that researcher may have as a teacher, but IMO undergrads will probably learn more at a community college because the professors are actually there to teach.

I still wouldn't recommend the community college because the diploma from there won't get the graduate as much respect, but I do know a community college graduate with a bachelor's who makes way more than I do. She had trouble getting her first job but once she had some work experience, employers cared a lot less about where she studied. I also know another graduate who got her associate's at a community college and then transferred to somewhere more prestigious; she saved money without compromising her education.
