How to choose the best rotating proxy?

I'm parsing data for a project and need a good rotating proxy. I've tried a couple of options, but the speed and stability leave much to be desired. What proxies really work well and do not hit my wallet too much?

I use the best rotating proxy from one service for parsing data, and I can say that they are quite reliable. The speed is normal, and the proxies change automatically, so you can work for a long time without blocking. I liked the fact that their service supports a lot of locations and allows you to flexibly customize your work. You can check it out here: https://floppydata.com/proxy-type/rotating-proxy/
