I agree with everything said above. However (and I keep records), the number of MK kits appearing on ebay has definitely declined in the past year or so. Eureka sells kits for several of the older pattern designs (Atlas, Curare, Super Sicroly) that were kitted by MK. There is a gentleman from Korea (hobby shop owner) who seems to have a large stock of MK kits which he periodically lists on ebay (he has 2 of the newer 3D MK kits out there now), but his prices (including shipping) are not cheap. I suspect there may still be MK kits to be found in some of the good Japanese hobby shops; I'd like to take a hobby shop tour of Asia someday (like when I win the lottery ).
The new pattern kits available from Japan (Wingray) are true works of art, but you will pay a premium for them.
MK apparently ceased kit production about 2 years ago. They had produced the Curare, Blue Angel 60 and 40 kits in the past decade. Anybody know what the story is with Kato Model Products?
