We saw Orlando Magic v Detroit Pistons a few years ago and it was extremely cheap to get tickets. About $10 each, I recall. We parked very close to the stadium too, I think. Tickets were waiting for us at the box office, booked via Ticketmaster.
While it was an experience, I'm not sure I would rush to go again. It got very tedious with lots of breaks, timeouts, cheerleading etc etc. More entertainment than sport, I would say.
Certainly not at all comparable with English Premiership or Championship football games.
Massive choice of eating options at the venue too - not pie or pasty like the UK!
Also found the sticky floor to be a bit odd!
