I "bit the bullet" and have no regrets. I thought it was pricey too, until I looked into it (no,
REALLY looked-into it, by opening-up the dash to the point of seeing what is behind it).
And yes, while each mode button can be overridden using an individual delay circuit I submitted in earlier in this thread for each mode button, it cannot be done without voiding warranties, or being able to re-install the back-plate using the same hardware. It could be done for around $10 per switch and 5 hours labor.
When I got the SmartStopStart module, I saw WHY it was priced so high... I opened it up.
Obviously, I voided it's warrantee (they come with an awesome one), but I had to see for myself what was inside the case.
Being very curious about this stuff due to my hobby and background, this not my first warantee-voiding rodeo. I do it to most of my new electronics, "
to hell with guarantees, the education is usually worth it". My poor DD is in for a rough life in that department. I can just SMELL the mods coming later!

By my estimation, it would cost me about $70 for the components, then would take me about 14 man-hours to make the PCB and assemble it. This does not take into account the original R&D and design time, money and talent that I, or someone else would have to come up with for the concept on-paper, then the first prototype build.
I'm sure once you gear up for producing these, your costs would reach somewhere around $100 from components-to-assembled per unit, on a production run of 100 units or less. So at $100 per unit, that would be "breaking-even".
That is just my personal "guestimate", but long shory stort, the gizmo is worth the asking price. I'm 100% glad I bit the bullet.
