Just got a MISB Encore Convoy off ebay for $100 last week. That will be the easiest long stack version to get.

As someone who is very concerned about KO's I'll point out that any "reissue" thats in what looks exactly the same as G1 packaging (Styrofoam insert, box with the old Hasbro logo it) is a KO. Actual reissues have some minor variation in packaging.
