I am selling an "extra" Apeks DST DIN first stage. I purchased the reg used, and it was serviced within the last year and hasn't been in the water since then.
It can be yours for $80 shipped within the continental US. I do not charge extra for PayPal.

This is an older model with one 1/2" UNF ports (it is plugged).

Of course with any life support, you should have this checked by a qualified service technician before you use it.
