It's discontinued now but I hunted around a bit and found older references to it selling for around $100. I even found one surplus supplier that has some new for $109: ShaverMCM Part ES7006Panasonic Part ES7006
replacement comp for panasonic er224rc can be found at amazon (for best price and good seller review). take a look on this one Panasonic ER224 Beard Trimmer Comb Attachment I hope this was helpful. cheers
