I am not too big on KO's, however they can be a surprisingly nice addition to the collection time to time. So far I have G2 Devastator (found on eBay for 25 dollars) and the quality is pretty good (although I try not to make a habit of buying any KO that is a direct copy of an official release). I also have the 6.5 inch Fortress Maximus (also found on ebay, 18 dollars) and I really like that one. Next up I am thinking of buying the oversize PE Reflector in G2 style coloring with neon green, blue, and purple (iOffer, negotiated down to 24 dollars from 27). I found out on Chimungmung they had an oversize purple G1 Blitzwing, but it's sadly sold out. Wish I cold find one of those oversized G2 Bruticus sets as well. What are some you own or have seen and would like to share?
