Sub-compact 2x cranksets with power (46/30 to 48/32) - Help me make an inventory of current options

I have stock Praxis Alba 48/32 on my Diverge - I was searching for a dual-sided power meter (spider-based preferably) with alloy crank arms for under $700 and can’t find anything - do they exist at this price level?

I have the Pioneer Ultegra on my road bike and it’s great (also shows force vectors and pedaling efficiency) - got it for $700 on sale. Can’t justify spending more for my gravel bike though as I hit the cranks on rocks at times, plus in general that power meter will have to put up with offroad conditions. I’ve dented by front chainring a few times too, so looking for something where chainrings don’t cost too much.
