Go for an AC110, I own 2x110, 1x70, 1x50, 1x30, 1x20 and all of them are running in my room. The loudest is the 70 because it's probably 15+ years old and i haven't replaced the impeller yet. My 2 AC110s are the just as quiet as the smaller ones. Look on ebay and craigslist for some, I bought a 110 for $40 free shipping brand new on ebay, only thing was part of the output was broken... 10 minutes, some super glue and duct tape later, brand new filter. They run like a dream and have HUGE media options and capacity. Believe me, it's what you want.
