I cannot tell you about fair pricing. That is up to you.
I owned Spacedecks with both platters and I found the taller platter version pretty much as your person described. Still very good, but less lively and musical. Contrary to what some might otherwise think, I found the shorter version better in the area of speed stability. Place a Boston Audio Mat 1 on the short platter and you're set. In addition, if you can get one with the Spacearm it will wholly outdo the 250, IMHO.
