The Hearing Club for Flexstrips $20-a-pair → Programming Adapter choose size 10, 312, 13 or FLEX STRIPS Comes with two adapters
Though, watch out because you may end up ordering programming pills by mistake. The two are side-by-side and are very difficult to distinguish which one you are ordering.

Hi Pro EBay - Make sure it’s USB, I saw a serial Hi Pro (with no cables-nothing but trouble) for sale on EBay.
CS44 cables?? I dunno? All I see on EBay are Phonak CS44a cables which have pins 3&4 reversed. Maybe these are getting hard to find?
Tip: when searching add “hearing” to help find cables for hearing aids.
