At that budget? A basic nVidia Jetson Board, a fancy mono sensor of choice, a bunch of extra CSI lanes beyond reasonable scope and I'd prefer to enjoy/embrace a software first pipeline/workflow stack for the data akin to gnu-radio-companion. That's where my itch would be. At this budget I'd want to be experimenting in the stitching sensors game. I'd prefer focus there if I'm throwing money away. Otherwise I'd scratch the itch more wisely with a pi stack :(
