I like Digital Ocean droplets very much and they are not expensive and they offers SSD based disks. Depending of your needs for the vps is the cost of course but the minimum $10 per month you can start with your deploy. Also if someone invites you, they give you $10 and $25 for who invites you. They give you the droplet(vps) in 55 seconds. I recently do some research about this for our infrastructure and https://digitalocean.com is the best option in my opinion. Here are the prices:
