Do you know what controllers come with the track? They might be absolutely perfect for the medium-term...

If the reason to get a more expensive controller is to race competitively at a club, personally I would wait until you start going to club, see what other racers are using, what they suggest and see if you can have a play with them - even just holding the controller and testing the feel of the trigger. There’s a good chance someone might loan you a controller to race on your first few visits and might offer you something to buy that is surplus to requirements. Clubs are good like that!
