I think Henke has explained it as honestly as he could.
When your ready to drop around $4000+ then you can join the turbine world.
Your stubbornness to fly ONLY a scale jet as a first, is a BIG mistake even if you can afford it.
If you change your mind and decide to fly a trainer such as a Boomerang or Tornado.. then your options will open up as there a many for sale in the RCU classified and you can get one that will possibly be under $4000 even $3000
There are several trainers here for the price range I have mentioned
