Not the cheapest it's been all time (around $260 at David Jones a year ago), but the cheapest I've seen it since the price hike two months ago. Since then it's been hovering at around a 'discounted' $310 - $320 given the new $350 RRP.
Fun mechanical build and nice display piece.
Can confirm it went even lower than that as I paid $247.49 from Metro Hobbies via eBay in November. It was obviously some 25% eBay coupon deal as the original listing was $329.99. I feel like this is one of those sets people will pass on, and then want later when nothing comparable is released.
