Sounds like you're flying a dog - May not be the type - just the example. I've never flown one that did not have a "hot mike" facility, and if one stank - i'd find out why and have it cleaned.
If you test drove a second hand dirty smelly Jaguar with broken electric windows, would you tell everyone that Jaguars were dirty and smelly and that the windows were rubbish - don't think so.
Give the Jet-box a chance and you'll grow to love her. She's not a Gazelle (and don't forget it or it will kill you), but treat her nicely and she's great! If you're not happy with the one you're flying - find another.
Best of luck!
