I think RANT is great but too expensive. Instead I bought an older version of Flight Sim, like 2004 for £15 which runs well on any modern PC. If you put it on autopilot you can practice all the approaches in much the same way as RANT, and can have a look at the shape of your holds and procedures just the same with the map function.
RANT will be expensive as long as people keep paying £80 for it, in much the same way as airlines will keep taking those who pay for the type rating as long as people are daft enough to do so.
