Hobbit,
I'm actually a member of Brickboy that has outlets in Gardens, Sunway Pyramid (which has unfortunately been closed) and as you said, Tropicana Mall. I've never however been to the one in Tropicana. The last time I visited them (which was way back before Sept 09), the MF set was tagged at about RM2000+ (I can't recall the exact price). But I'm not sure whether it still holds that price seeing that the model has been discontinued. If it does, then it's a miracle!
When I was in the UK, my interest in Lego had however waned so much that I never even visited the Lego stores, such as the one in Bluewater, Kent which is not that far from my home. I did visit some of the toy stores, e.g. Hamleys, Smyths, Harrods, Toys r Us, etc. but even if they stocked Legos, the MF set is never there. I guess it's really a collectible now. How I wish I've got it then.
By the way, if you're interested in witnessing how each of the 5195 pieces of the MF is painstakingly assembled in 3.38 minutes, please click here:
