Only place I've seen them is TRU.... had about 20 of the dark ones and 20 of the light ones.... they had a LOT of dlxs....lol
My TRU was almost all out of deluxes. My guess is that the changes to Sideways and Skidz were made to fix production errors and/or make them more accurate, and thus the light colored, toothless toys will turn out to be the rareties in the long run.
No not rare. It's a running change that was made to the figure. The light colored one was produced first (as is the case with Breakaway), then changed to the darker version. For the most part, taking in all the sightings, there seems to be plenty of both around the country. It's just one of those things that while one store might have it, the other will not type of scenario. This same scenario is also happening with these two as well (although, in my area, Rampage is readily available in all stores). Soundwave turns up in tons at one spot, but never seen in another.
