I'm using the Probotix drivers and you are right the motors get quite toasty particularly since I got the 40 volt option. Trade offs are always a challenge. I looked at the V90 purchase as an initial learning exercise. All of the forum reading in the world won't nail down the importance of stiffness, squareness and dozens of other practical matters like getting first hand experience. The trim routers are a little heavy for the V90 as the y-axis rails have enough flexibility to allow the router to twist some with high cutting forces. It has impressed upon me the value of full supported rails on all three axis. Good luck on your adventure which ever approach you take.
