The dynamixels are fairly priced when compared to equivalent servos. Compared to the weakest slowest servos with lots of dead band slop the dynamixels are quite expensive. However those servos are quite useless of course, and compared to servos of similar built quality the added cost of a dynamixel is minimal. Look at something like an AX12W dynamixel which costs $25 more than an equivalent Futuba S3003, roughly same torque and speed. Given the control capabilities of the AX12 I don't see the point of buying the Futuba product. Or a Futaba S9452 is about $90 for 130 oz-in of torque or Dynamixel AX-18A for $95 for 255 oz-in torque. Eh an extra $5 for twice the torque, not that ridiculous. There obvious scaling problems where putting a vary fancy controller on piece of junk mechanicals doesn't make economic sense so you'll probably never see something with the control features of a dynamixel on sale for $5 each.
