I can confirm having a good experience with Communiteq. Good, fast support, good pricing, good base feature set (e.g. some plugins included even at base hosting level). That said I’m not sure what you mean by “7 subdomains”, if you’re referring to 7 separate forums, but the pricing may not work for you in that case.
If you do need 7 separate forums with a $60/mo budget, then self-hosting would be the only option within that price range AFAIK. And at that point the question becomes: why are you leaving Digital Ocean? Since it appears to be widely recommended as the best affordable self-hosting option for Discourse, it’s important to know what about it did not work for you, in order to suggest alternatives.
