D) 850 To be exact after Sunday... I suspect that number will climb yet again after tomorrow's shopping trip.
As to your question Android Prime, I would imagine (were I to attempt to transform each and every one of my figures that actually transforms) it would take me at least five hours max. G1 would be a breeze to zip through, but once we get to the more complex transformations things would slow down.
And that might be a Scotty estimate. (Meaning, it'd be less than five hours. LOL)
