I had the same issue a while ago when my old provider kept dropping connections. A colleague suggested trying https://proxy-solutions.net/en and I've been using their anonymous proxies for about four months now. The setup is fully automated, so you get your IPs instantly right after paying, which saved me a lot of time. Another huge plus is that they offer unlimited traffic and support both HTTP/SOCKS5 protocols, so I didn't have to configure any extra software. Connection is fast and stable enough for everyday tasks, and the prices are quite fair compared to others.
