Price isn't bad for what it is but the part is massive and quite hard to look at....however, in a racecar, it's not much of a deterrent. There isn't much need for a sequential on a "street car", to me.
Offering a gear counter would be nice. My ECU will give me a calculated gear indicator, but a non-EFI car wouldn't give that feedback. It's not vital, but nice to have.
If I was in the market, I'd like to know what their plan is for not needing a clutch before I trashed a set of syncros. I am not sure how a shifter assembly could overcome that, even with a shift cut input to an ECU.
