How do I find suitable proxies?

I often use proxies for different tasks, but I'm tired of looking for suitable proxies. Is there a service that offers a large number of proxies with different geolocations, authentication methods, etc.?

My question is still relevant.

For business tasks it is best to buy proxy packages. It is profitable and convenient. I often buy proxies for parsing and other tasks, it works well. It is convenient and profitable to find proxies through such search engine.

But how did you choose specific proxy providers? All providers offer roughly the same terms. Focus only on the price?
