30 from Rochester here moving to Mt. Pleasant next month (with wife and son)!
Check out this thread for complexes in the Mt. Pleasant area:
Mt Pleasant Apartments - impressions of a mom and son
Also, check out the listings in Apartmentratings.com as well. I was pretty impressed with some of the reviews of some places not discussed in that thread. We are going into Riverwood because of the 3-bedroom option, the timing, and the ratings on that website.
I just found out this week that Comcast and Knology are your potentials in Mt. P, but Knology isn't everywhere there. Satellite is an option if the complex allows it (Riverwood does not). Ask the complex managers if they have sales rep associated as you will get the better deals through them than phoning their call center.
