After alot of looking around id figured id start with the MP-10, G1 based, probably the version 2 KO, as i guess thats the cheapest of them, and replacing to the articulated hands eventually

Im a bit stuck on where to buy and what to search/look for, as they vary alot in price, and figured it was best starting here and hopefully not waste money on something that looks like a cheap ko!
Any tips for a new collector on what to look for, and maybe some god ebay sellers?
Not really looking for the trailer, and loose is fine, what price are they usually going for?
This one seems to be too cheap? I get even more sceptic when the trailer is included, as the KO only comes with weapons, and not in a square box?

Does this seem legit?
