You think if btc-e was to steal money, they would steal just your $1000? $1000 for them is a fraction of a peanut.
If they were to steal, they would pull a gox on all of us.
I suggest you get in contact with them AND your CC company to follow exactly where the money went.
I am not saying they would never run with the money, but they would certainly not run with just your $1000.
edit: I withdrew 3 times to paypal and twice to VISA larger amounts than yours, and had no issues so far. I agree that their communication seems to be very slow but 6 weeks is far off. Did you open a ticket? Open another ticket if so and try again.
