You are right - I think it depends on how much you want to spend and if you want the valve to sit on top of the shut-off lever or a ball valve that requires plumbing work. Also, the size of your pipe/Lever will matter. I have a 1 1/2 inch pipe and Zooz customer service was not confident their valve would be able to handle it - I wrote them an email a while back.
I just installed a dome valve ($99/Amazon) and it works just fine. Install took less then 15 min without any issues.
