How much bandwidth do you currenlty use? I can't see 200 people using 500GB of bandwidth. Bandwidth is something a lot of people overrate for themselves. Think about what you really need, and go with that and then hopefully your provider makes it easy for you to upgrade.
You are right. I really meant LunarPages, they offer Windows hosting but not as a VPS. Their VPS run on CentOS, so it doesn't fit this profile.
Servint suggestion wasn't also for this case. I skipped the Windows part on the first post. I was thinking about the title, and Servint was on my mind. I'm not affiliated with them. Just a previous user.
This is for an unreliable service I take it. 500GB BW costs more than $60
GS RichCopy 360 Enterprise - Voted #1 for data migration and replication in terms of performance and features. Replicate data across between servers in the same network, WAS, or even across the internet
if i get a relaiable host i am willint to pay 20 or 25 $ more
I thought you said $40-$60 in your initial post... If you really need a RELIABLE VPS for the use you are reffering to, you must look for a Fully managed Linux VPS with 384MB (or greater) of RAM running Plesk, PHP, MySQL, etc at a price range of about $60 or greater.
