Congrats on the CFI!
My type ride was free with the local FSDO, but the plane and copilot (also a DPE) cost a bit. It was similar to the Spanish Inquisition, slightly shorter in length, but the ASI is a true aviator. You knew when you finished you were qualified or not qualified, no BS busts or passes. I hope the ASI becomes a DPE when he retires from the FAA. Aviation needs more people like him. (Just don't get on his bad side...and if you're there, get off of it quickly.)
My MEI was $400. It was wasted money with a Santa DPE. The particular DPE must be politically connected as the local FSDO knows about his rides, but won't do anything about it. He's featured on a forthcoming movie about the airport, too.
My Airframe Mechanic Practical was $500 and took 14 hours with a short break for lunch. I offered to pay the DME overtime, but he refused.
My CFII with a decent DPE was $250.
The CFI in Vegas cost $250 for the DPE, after I passed he refunded the whole amount, stating I would be sending him students to make up for it.
The commercial in Vegas with a retired ASI was also $250. He only *looked* like Santa Claus.
A student taking his instrument ride today will pay $350 in Socal for the privilege. A private applicant paid $250 for the first take, an hourly rate of $50 for the second take in Central CA this past summer.
