The thing with re-boxed kits is if its something you´ve been after for a long time, then its a Gods send! But when you´ve felt you´ve been ripped off ... not so nice.
For me, and probably others, that are still fairly new to this game, that might be the only chance we have of getting some of these older kits. Its just a pity there are so many crappy rebox sets instead of some of the older decent kits (there have actually been a few oldies but goodies released recently).
Im sure there are sites that have reviews of a lot of these older kits thats worth checking out first ... or Ive even seen a lot of folks ask here for a quickie review from anybody that has built it. When items are going so cheap on the likes of E-bay..... it may be worth checking out first if your attracted by the bargain. But if its the something you´ve been looking for, for a while....... I would be happy enough!!
