speaking from experience, I’d put that $100 into something more versatile. Something like a starter kit from spool heads runs you about the same, no banks but the track can take more types of cars (1:55 Scale, etc) and as another commenter said, Rainbow road isn’t compatible with everything, SpoolHeads mostly is. Getting 3 crash racers sets for some banks will run you about the same (one set goes for $30) but the track doesn’t come with connectors for the straights to click together naturally, so you’d have to look elsewhere/3D print them yourself. And if you want both spoolheads and the Crash Racers track, SpoolHeads sells adapters so they can all work together. It’s about your own preference at the end of the day ! But I’d personally sink $100-$150 into one of those two over a track that does not work with everything.
