Like most manufacturers - Hasegawa has only recently started producing new 1/32 scale kits:
Bf 109 G/ K series and a Fw 190 D-9 series.
These really are superb kits - and while lacking all the "bells & whistels" of sa ythe Tamiya 1/32 Zero, they are very afforadable - and a joy to build. I can heartily recommend these.
Their older kits e.g the P-51, Hellcat, Spitfire, F-104, A-4, F-16 date back to the 70's and 80's - and while these were good kits for their time, they are starting to show their age.
That said - they can still be made into superb models.
