From my perspective:
This is the list of parts on my gravel bike equivalent to the Ultegra R8170 Groupo. This combo cost me less than Scumano, weighs significantly less. (I spent more than I would have had to by installing 48T, 32T rings instead of 34T, 50T.) I agree 100% that the current asking prices for the EDS TX is silly money compared to DI2 or SRAM offerings.
OTOH, we will see what sale prices are during the 11-11 sale. - I want to purchase another EDS TX for my road bike.
EDS TX kit - $515
Raceface Next R SL - E-bay sale $199.00
Race face spider - $25
Race Face bottom bracket - $45
Chainrings - 48T, 32T $50
KMC 12 speed chain - $32
ZTTO Ultralight cassette -12 spd -$85
Rotors - 180 front 160 rear - $30
Total $981
