I'm looking for some cheap private proxies or semi-private proxies that work. I'm looking to pay $1 max per proxy. Going to use them for stuff like GSA SER or Scrapebox. I need them to be able to run multiple threads at once. I mean i run GSA SER with 250 threads (or more) and i don't want to buy 250 proxies. Let me know if you can recommend any reliable provider. So far i've tried instantproxies but the proxies go down too often.
