I got WRZHost for my semi-dedi as you know. I love have the ease of use of a shared plan with the resources of a VPS.

As for plans site that require a semi-dedi should include plenty of bandwidth. With a minimum of 75gb for a basic plan.

My site is only a 2 star on Katz with an average of 2,800 unique visitors a day and i got through some 60+ bandwidth a month.

So if my site being this small uses that much I can only imagine a large site.

They should also come with a dedicated IP standard.
