i ended up paying 119 and change for mine.

after all of this is said and done i'm going to look into doing an IB setup back there. unless i just love how the prefab box sounds. i pulled the sub up in winisd just for shits and giggles, and the box i'm putting it in is within .05 cubes of the ideal sized sealed box it came up with, so i think i'll be good to go here.
