If your home base is a finite demiplane, however, an Amulet of the Planes might be even better choice however, as long as someone in the party has 20 INT, in that you don't have to leave a portal behind.
A Mirror of Mental Prowess is, however, the best choice-- if you can afford it. Placed in your home base with a loyal operator, the Mirror allows you to just verbally ask for a portal home and have your loyal staff open one for you. Not only is this method completely invisible until employed, it's also completely immune to any trouble you might be having on your adventures; even getting disjunctioned by your enemies, stripped of your belongings, knocked unconscious, and left for dead on the side of the road wont prevent your loyal minions from showing up to rescue you once nobody's looking as long as that road isn't also in an antimagic field. Just make sure your mirror operating people are very loyal, and your home base is very secure.
