I just moved from Maryland to Texas, so none of my sets are assembled right now. I can provide a list of the sets I own though, as I took inventory of all the Bionicle sets I own for a project. Beware: there is much text for all the sets.

2009: All of the stars (tahu = 2), 1 Toa Mata Nui (minus golden mask plus silver mask)
2015: So far, none, because I haven't made it to the Lego Store yet. AAARGH!!
I got a few of the playsets (the lego sets); the two shown by Artahka-the-Creator (Piraka Outpost and Lava Chamber Gate), as well as Race for the Mask of Life, which came with two vehicles and a small gate.
I also have several incomplete sets and a ton of extra parts, including three of the huge parts tubs back from 2003. I also have several collectible masks, including a chrome silver hau.
Oh. I also got Click the scarabax beetle.
EDIT: I'm stupid, I combined what would be 2004 and 2005 into one year. No wonder I was one year short. Oh well, you get the point: the sets, not the years.
