Use Digitalocean.com. It is the best and most stable VPS provider I have ever used. You pay between $5-10 a month depending on the RAM you need. The best is, you can use one of the many free vouchers to get 1-2 months for free. Use Google to find valid voucher for this month.
Digital Ocean is grossly overpriced for what you get.
Digital Ocean charges $5 a month for a plan, when you can get a similar plan on other sites for $10 a year.My suggestion to the OP would be to stay away from Digital Ocean if he's looking for a cheap VPS. Even with those free vouchers you mentioned, their prices are extremely high.
