You machine (iMac 27-inch, Late 2009) will take a max of 16GB DDR3 1033MHz (PC3-8500) RAM.

Both Mushkin and Corsair do Apple Qualified RAM, and I've used both with good results. I've got 16GB (4x4GB) of Corsair in my father's iMac (27-inch same as yours, Late 2009, but i5), and 16GB of Mushkin in my 21.5-inch, Mid 2010 as well as 8GB of Mushkin in my MBP. I've also installed a LOT of NuImpact Apple RAM.
