This is only slightly related - I lost a small number of files with DreamHost object storage, and they were charging more than S3 per GB.
So, I agree you usually get what you pay for, but also make sure the provider is all-in on the product. I think DreamHost really isn't interested in their virtualized/cloud offerings.
I installed the Fakespot extension and then went looking through my past purchases. It seemed to work really well and called out things as shady for products that I can say, first hand, were actually kind of sketchy.
