Well I went to a 24 hour walmart and they had about 25 R2-D2 figures on the pegs. Now here is the talley of R2-D2s with different legs that I looked at.
I got to look at 11 R2-D2s
10 R2-D2s with the R3-T7 legs
1 with the dome style legs
Now was it just this store or are most of the R2s being found with R3-T7 legs?
So far it seems that the dome style is the rarer of the 2 around here.
post your results and maybe we can figure this out.
