The cheapest Cessna (say a half-a-century old Cessna-150 with only a thousand or hours left on the engine before mandatory refurbishment) will set you back maybe $20k.

Then there's the maintenance costs (one every 50 flight hours, a bigger one every 100 flight hour and so on as well as the yearly one), plus insurance and fuel.

Oh, and flying one of those planes is not really excitting (except for landings, those are cool) mainly because it cruises at 90 knots airspeed (about 160 Km/h) which at the minimum flying height per flight regulations (except during takeoff and landing) which is 1000 feet (around 300m) does not feel at all fast.

Absolutelly, spend $30k (if you get it as a kit and assemble it yourself) and you can get something a little more excitting ... or spend $2k in that setup (I'm guessing, assuming you assemble it yourself) and let the Suspension Of Disbelief save you the rest of the money and you can even fligh planes that cost many millions of dollars (which, judging by the controls, is what that setup is simulating).

Mind you a Commercial Pilot License is "only" 1000 flight hours so you might get it for less than $100k depending on which country you do your training in and hence the cost per hour in the air (or, if you do like my Amateur Pilot Trainers in the UK and give lessons for the flight hours, which can be done with only an Amateur Pilot License) though you'll get a lot of "special moments" with trainees at the controls (did I mention landings are exciting ;)).
