+1 Vac pot
Just order the size you need and no bigger. They work best at full volume, and it's better to have to brew more than to leave coffee sitting. Also, for me, it comes out screaming hot - so give it a minute before you start drinking. Finally, at least while you are dialing in your technique, a thermometer is essential in knowing when your upper-bowl water temp is right. I use one every time.
