Just curious......

I think the number you choose, won't give you much information.
(but then, i don't know what information you are looking for :) )

1-5
6-30
31-75
76-125
126-175
176-255
256-more

Would be more intresting in my opinion.

I host 110-135 sites on a raq (i don't mind if its a raq4 or raq3).
They have 512Mb ram.
