Tarot 450 Pro V2 or HK Assault 450DFC TT

I have an older Walkera FBL 400 heli. I may have just purchased the last motor available for it. It goes through brushes like crazy, but it's fun to fly and super quiet.

I wanted an Align T-Rex 450 (3S) because I thought I'd get parts locally but everyone stopped carrying them. Second, HH stopped making a 450, bleh, no parts there. So local parts is off the table at this point.

Anyway is the Tarot 450 Pro reaching the same point with parts?

From a parts availability perspective, are both helis still going strong?
