Look at your current usage and double it at least, triple is even better because coming half way through the month and running out of bandwidth is probable the worst thing you can do for your website, your users will probable desert you, if they see it isn’t online for a day or two.
I recommend NetShop Isp
Cyprus VPS to all webmasters looking for reliable and stable option to host their web sites!
I love the speed of the site, the uptime, the support when needed and the features (the automatic backups are wonderful especially).
