Hasegawa 350th Scale Soya Question

[Captain Canada]

Hi guys,
   I am thinking of getting one, but seem to be running into some confusion about the kit itself. Has anybody bought one ? Are there 3 diferent kits ( 1st, 2nd and 3rd Corps ?) I really want the one with the S-58 and Beaver ( this is where Wooksta! comes in, and offers to make copies for us  )

   Conversely, are there any other 350th scale Beavers available, so I wouldn't have to buy an $86 model kit ?
