looks like a solid stackup! i have similar to this one..
it depends if you really need so many power planes.. tell us about you project?
reason for asking is that in some case you might be able to do it in a 6 layer stackup
if you need 4 routing layers to fan out your design.. you might not need all those gnd / power planes..
somehting like Top / Pwr / sig1 / sig2 / GND / bot, might be a good enough option and save you, money..
it all depends on you design.
