I've been debating picking up a MISB gray G2 Grimlock for a while but the prices on Ebay seem to be all over the place. I've seen supposedly new/sealed samples go for $50 and others go for $300. I know the MISB blue versions tend to start at around $300 and I haven't seen the crazy price fluctuation for those that I've seen for the MISB gray version. Were the ones I've seen around $50 an attempt at a resealed knock-off or some such or were they likely the real thing? Guess I'm just paranoid about if it's too good to be true it probably is... Thanks.
