I saw all four figures at Target last night. I only bought the X-Wing Luke for now. Darth Maul and The Sandtrooper were tempting.
R2-D2 was a very easy pass. Looks too small. One of the legs was really warped in the package. The paint was very bad and sloppy.
I thought the R2 seemed like a bad value to me as well. It looked neat, but $20 for him just seemed way high. I did grab the Luke and Sandtrooper. Still not sure about Maul, R2 and this line as a whole, but I'll check out the first two and try and make a call at that point.
