This is one of several sites that I use to learn about VPS servers. Also I use the site to learn about WordPress as well as trying out different FREE Control Panels. I currently like and use CloudPanel.
This site is from Racknerd and is a 2G Memory and 2 CPU VPS for about $18 a year.
Below is a link to a really lowcost VPS with a control panel for only $5 a year.
