OVH ( USA ), BuyVM, HostUs, Scaleway comes to mind at low prices and good reliability
I've personally used BuyVM , HostUS and Scaleway before
BuyVM - 100% Uptime for the 2 months I used it, and excellent performance
HostUS - Had a few minutes downtime, good performance ( on SSD plan ), HDD plans are quite slow
Scaleway - It's good, but combining storage blocks is a pain, and it's routing outside France is terrible ( bad ping/latency to USA )
