Carrera models can be twice that price $1,200-$1,500US Some of the Autavia models can be had for about $1,000US and more. Again prices will vary on condition, movement type, and the bidding action. Good luck in your search.
I would recommend that you spend time following the auctions and other watch sites to get a good feel for the going price and to fine tune your internal lust meter. There are a lot of cool watches out there and after a while searching the right one will speak to you like with the sweet song of a siren. LOL
Then you can hunt for your next one. ANd so it will go. After that you will be a certified collector nutcase like the rest of us. LOL
