Lately I've been picking up vintage G1's to flesh out my childhood collection (they are more fun to fiddle with than MPs IMO), and I had a bunch of Pretender Monsters, and having always wanted to complete Monstructor, I've been thinking of picking up the guys I never had. HOWEVER... they are both notorious GPS sufferers. Despite owning many tfs from that era, I've never owned one that had GPS, I'm wondering if it's worth shelling out the big bucks, trying to assemble Monstructor, and have him crumble before my eyes. Of anyone here who owns Monstructor, how gingerly should he be treated? Do you keep him in combined form, or is it too risky? I'm really on the fence as to whether I should buy these guys, are they going to crumble if I look at them funny, or is there a reasonable amount of care I can take before they die painfully? I did a thread search, and I see people do have them combined, are they still in good form? Has anyone had Monstructor turn to dust when combining him?
