Atlantic.net offers VPS hosting. They interest me because they offer a low-end VPS for $0.99/month. You read that right, ninety-nine cents per month. The specs on it (256MB Ram, 1 vCPU, 10GB disk) probably only make it useful for dev work, but their quick deployment (30s) and 24/7/365 live support have me interested in trying out their offering sometime.
