Momo start is a great value. 96% of the higher end seats performance-wise for 30% of the cost. I have been known to be dozing in mine on grid.
I'd rather save a couple bucks on the seat, then spend the savings on an Isaac which gives you so much lateral support in the event of an incident. (As opposed to the same money for a HANS, but then you HAVE to pony up for the special seats to get the same relative level of protection. YMMV.
