EK1 tuning services

Based on my research SXTH (their recent ots tune bundle) and cherry tuning offer ecu tuning via ek1. It seems n75 requires you to send in your ecu or buy tuned spare ecu. Need input from those who recently did ek1 tuning to update the available tuning services. Also I know previously you can find different tuning files via sxthnk but they are no longer available as of now.
