I have three hosts I use.
Each of them, it is a reseller hosting plan.
Though I do not resell hosting (not worth it and too many problems).
But next month, after I have sold off a bunch of my sites and blogs (yes, going to unload and drop to between 4 to 8 blogs only), I will only have one host.
One host to use is dualrack.com.
Especially if you need proxy hosting and/or adult hosting.
