There are a few options in 1/72, from Italeri
and Hasegawa
.
Most seem to be standing, I assume this is partly due to the lack of space and inconsistency of cockpits in this scale - "off a little bit" quickly means you can't fit a pilot on the inside anymore.
You can always start with the upper body of a standing pilot, and use chopped-up leg pieces and putty to fashion a seated pilot as well. Most of what will be seen is upper body anyway.
