Man, these knock-offs are pretty impressive with respect to the level of detail; with the obvious exception being the price. It's pretty hard to tell the difference from an untrained eye (i.e. most comic book/toy/collectible store dealers that I've dealt with). I bought the Frenzy/Lazerbeak knock-off a while back for a reasonable amount, $40 CAD, (the dealer made me aware of its deception prior to me purchasing it) and I've got to tell you that it looks amazing from a display point-of-view (which I guess the whole point of these figures are), but the prices are sometimes too high. I found another dealer trying to sell the same F/L knock-off for $180 CAD and he thinks (or pretends to think) it's legit (I've told him otherwise; although he has yet to reduce the price). I wouldn't mind seeing knock-offs of Mirage, Ironhide, Ratchet, and Sunstreaker released. I would ignore the moral issue of purchasing these since Takara and Hasbro insist most of these will never be re-issued because they've "lost" the molds (so it only seems fair to upgrade beat-up 80's versions with fairly accurate knock-offs like Frenzy in those most economical manner, as long as you don't try to re-sell it as vintage, of course).
