Digiprog3 and ST 01/2 cable used is China clone.
The entire kit cost $169, with a set of cables and adapters. But i don’t think everyone should buy the entire kit, for the main unit should come with ST01, ST04 cables, which will save $40. Of course you should use st01/ st04 or have other adapters in hand.
