See, that's the beauty of opinions.. You found those items to be overprized, I only found them to be expensive, and understood why they were expensive. I bought them, and enjoyed their benefits so much, that I suddenly realized the benefits justified the costs.
I also thought I was being rather relaxed... If 1 teleport location costs 5950g (at Exalted), then 30 times that would be 178500g..
Now, in reality, there are 50 tamers in the game. 49 in the world, and 1 at the darkmoon faire..
Sounds pretty decent to me to spend 1000g for a teleport to each and everyone of them, for the rest of all times.. 1000g x 50 tamers is 50k...
Since OP talked about a Stone, that could therefore be BOA, like the battle stones and the bandages are as well.
