It's basically going to be the exact same creature repackaged (maybe a VERY VERY slight paint diefference to pull in the completists. Plus, the EXACT Sandtrooper was abundantly released in the TVC line' 1st or 2nd wave, thus you've probably already got that(if not, it's easily found here in the classified at RS or at amazon or at rip-off-Bay). Therefore, my personal suggestion to you would be this:What should I get, TLC Dewback, or this one?
If you can find the "older" one("older" meaning that it was just released earlier, there is nothing "old" about it), ---many Walmarts still have them laying around in stray spots(and not always in the Star Wars section, so keep your eyes peeled), I would suggest getting that version, ESPECIALLY because many WM's have now had it on clearance for a while now (simply cause many of the boxes have been dented, slightly crushed etc). Thus, I would suggest go for that one if you can find it. Look through 2,3 or 4 WM's if that's possible for you. Believe me, this will pay off in the long run because this "newer" packaged set is the same price (more if you find it at clearance) for just the Dewback alone w/out even the figure & his accessories(for poking/prodding the animal included. Good luck my my friend, & good hunting.
