Combiner Wars Devastator - anywhere?

Hi All,
First post here so hello!
Am very late to the party by looking at it but I am trying to track down a Combiner Wars Devastator box. No one seems to sell them anymore and the only ones I've found are ridiculously priced.
Any ideas or places I can be pointed to that aren't eBay or Amazon? I'm UK based if that helps.
I have had one offer but was quoted 200 GBP. Is this a good price?
You'll have guessed by now I'm not exactly an experienced collector (more just looking for this one lot for my own nostalgia reasons) so any help would be appreciated.
Thanks!
