If it is a choice between Airfix style sets or Hat (ie between one new set a year and 12 new sets every release) I wil go for HaT everytime.
I love the old Airfix casulaties/unusual poses, but I appreciate the different commercial realities.
So unless they can be squeezed into the MAC "C" box I will pass on them.
There is probably a market for these from the metal manufacturers - I know that some are available from Germany, so maybe that is the company people need to push.
