Addition to Magic Item pricing - speed bonus (enhancement)

[JoelF847]

I came up with this formula for items that increase the user's speed:

Speed enhancements – for permanent bonuses to speed:
(speed enhancement bonus/10)2 x 2,000 gp therefore,

+10 speed = 2,000 gp
+20 speed = 8,000 gp
+30 speed = 18,000 gp

Good idea!

Could even be expanded to nonstandard movement modes (add fly speed, add swim speed etc.).
