I see this turning into another Spektrum vs. XPS vs. FASST vs. (whatever) religious discussion - already started here
(it's more entertaining in Czech, but you get the gist).
From a marketing perspective, it's already started also. Esotop.cz is claiming that Jeti is the best system (combination of FASST and XPS) and Spektrum is "relatively worst
" of all the 2.4GHz implementations.
Prices in Czech currency (Koruna) are included at the bottom of the Esotop.cz page.
So as others have said, it's time get some popcorn, sit back, relax and enjoy the show...
