fyi it's spelt "Devastator" and "Protectobots" (there's no "r") and yeah, there's no "i" in Megatron. That ought to help you in eBay searches etc.

Sometimes you can get bargains in auctions where toy names are mispelt because most people don't see those auctions, so there are usually no other bidders! - not that I ever find these bargains cos I nevre meak speeling misteaks. (actually, some people will intentionally do eBay searches with the names mispelt on purpose to intentionally find bargains from illiterate sellers!)
