An old rule of thumb for price estimation in consumer electronics is that the whole is six times of the cost of the parts.
Don't forget to figure in the cost of the PC boards, case, the power "cord", and the packaging. (back in the day of the vinyl record, printing the sleeve could cost more than pressing the disk)
The board they use is far from the cheapest possible - its a glass epoxy double sided board, as compared to laminated paper single sided, additive process (put copper where needed, rather than etch away where not) board that you might find in a high volume toy, or your TV's remote control.
