1 The OP doesn’t have a budget for Retail Sangoma nor Digium.
2 He found the “knock-off” clones on e-bay
3 His options are limited, if he wants a safe solution, he needs supported hardware , Sangoma and Digium only
4 Few machines have PCI slots anymore, thus the bargain basement prices in the “Gently used” market
5 I have never had a Digium or Sangoma Card fail
6 I have revived many third party systems that “went cheap” and regretted it.
7 I agree with @tonylewis
8 QED, no?
