Just for clarification,

The (2 seat) Extra 200 is a derivative of the carbon fibre sparred EA300L, recently introduced by Walter Extra, presumably to offer more affordable aerobatics (in terms of running costs) than it's larger brother.
The Extra 230 (from !!!!'s weblink) is Walter's original wooden winged aerobatic hotship from the 1980's, though still with the +10/-10g capability. It has not been in production for some time.
