1998 Honda Passport key stuck in ignition

My key is stuck in the ignition. I am able to turn the key to start and stop the car but am unable to turn the key beyond the acc stop to remove the key. I have read about other people having this problem and your answer and others. I dont work on cars and my question is do I take it to a locksmith or a Honda dealer because I have read about both. If I need the ignition switch replaced or if it is in the Park switch or if both need replacing what can I expect the cost to be. I dont want to be taken advantage of financially. I already went to the dealer and the first words out of their mouth was "the best we can do for you is $98.00 for diagnostics and go from there." My feeling is I already know more than they were willing to even mention by going on line in 2 minutes, I am female and dont work on cars and I felt I know more than they acted like they knew about the problem already. Please give me more information so I have a better idea of what to expect. Thanks. Oh, and by the way, I am periodically able to get it out by playing around with the gear shift. I dont know if it has to do with the button or the base that the shift is in. (Hope that makes sense)
