I received offers for 6 BTC someone offers more?

For the Escrow:
I would prefer not to use the escrow because I'm the only one that is not protected by this process.
The buyer can cheat both me and the Escrow saying that there is something broken in the Saturn, keep my good one and send me back one that had already broken.
Or mine with my Saturn for a few days and after send it back with any excuse.

The right process for me:
The buyer can be access remotely to the Saturn so you can view that everything works perfectly.
After the buyer checked, send me the BTC and I send the Saturn.
