Protostar 1.52" secondary holder and spider

I've got a protostar 3 vane spider and secondary holder that i need to sell to replace it with a holder that i can use with my homemade 2 vane spider. The unit is little over a year old and has small scratches where you'd expect from collimation but nothign that can be fixed. they sell new for around 75 bucks or so with the 3 vane option i think. i'll start the price off at $55 but you can make any offer you like.
