I like the little diarama, but the scaling is bad. As toys only, it is a little expensive for us in Australia (as a Voyager and a Cmdr is about $60 here), but REALLY expensive for those in America (as those two figures retail at about $30).
It can also depend on which version you've found, as I didn't think either one was released through a TRU store?

The one with the clear white Predaking was from SDCC in America, and the one with the translucent orange Predaking was from the AGC convention in Asia. Perhaps there was excess, or a TRU in a third country was allowed to release it.
What country are you currently in (or saw it in)?

Check some of the online stores for both versions, as the prices for both can vary from $40-100 on ebay... and neither one is consistently more expensive than the other (the Asian one looks to be rarer, at least in America, but the SDCC one is in higher demand because it was originally cheaper, looks nicer, and cheaper to ship as it was already in America). BBTS however, has the SDCC one at a higher price, while both BBTS and an Asian site has the orange Asian one at about $85.
So it's value will depend on what colour version of Predaking you want, or what "number out of the Anniversary 30" you want... or whichever is more convenient for you, as you obviously have direct access to one version.


UPDATE - okay, I can see what Asian country you are posting from, and they must have been given stock to sell in their TRU stores... which I'd be guessing is the orange AGC version?
