Was Searching For Good Rates And Alliant Credit Union (Chicago) Does Have Excellent Rates

Was searching for good rates and Alliant Credit Union (Chicago) does have excellent rates.  Their JUMBO rate for 48-60 months is 3.057 (3.10 APR).  Old institution which requires membership in area organizations in order to participate ($10 for membership).

I was trying to obtain ratings from Bauer Financial and for some reason could not find.  Anyone out there that can be of aid?  Interesting website: http://www.alliantcreditunion.org/.
