MP-8X is haunting me...halp!

[dalisprime]

So lately, I've been experiencing this weird craving for...Grimlock. Not just any Grimlock - the king of bling (rhyming not intentional), MP-8X. Been looking round evil bay and there are a few of them going for £150-£160 (shipping included), and one of the sellers mentioned he could declare lower value to avoid customs fees, but...While I can in a way afford it (as in get it paid with my credit card and then slowly pay it back over time), I can't really justify paying so much for, well, a toy.
So here I am fighting an ongoing battle between the rational side of me, and the big Grimlock fan side of me, and turning to you lot for advice. Should I give in and get it, or is the rational me right, and waiting for the not-so-shiny Hasbro release the only way to go?
