Another good choice is Solidproxies. Though I've personally never used this service, I'd read only good things.
I also know that Solidproxies offers an automatic replacement solution for GSA-SER.
(meaning, proxies that go bad are auto-swapped for new ones.)
Like I said, I've never used these, but if GSA is custom-coded to enable that feature ~only~ with SolidProxies, that is a certification of quality more valid than any of us users can offer you!
I feel redundancy is best. So, maybe it's smartest to buy from two providers and use both. This way, if there's *ever* an issue, you can keep SER running.
And, headroom is nice. Bumping up against your limits is not good. It may seem wasteful, but rather than operating at your limit, you will have space to ramp up.
Best of success with your proxy service hunting! Please let us know how it works out!
BTW, this is where you activate the feature to auto-replace banned proxies with Solidproxies in GSA-SER on the Submission pop-up window (See RED pointer arrow!)
( if this is new to you: you get here by hitting Options button between Delete and Start)
If you look at past feedback on these forums, SolidProxies consistently gets good reviews.
It's also unique in that the burned out proxies automatically get replaced in Search Engine Ranker. Not a bad feature to have!!
These are likely the best two choices. I never used SolidSEOVPS proxies but the reviewers on here are names that you SHOULD trust if you know anything about them; most are GSA experts.
I use Blazing proxies with different social media accounts and I am very happy with them, but any person can contact their support and ask about proxies for his needs.

They're both great in terms of price, speed, success rate and number of servers available. Basically all you can ask from a social media proxy.
Also, they both have great reviews on a review site called proxyway
Hope this helps!
