I'm with
http://www.x-gravity.net - I have a custom package from them because I know the owner. Extremely extremely good. Havn't had one second of downtime in the year I've been there.
My old host had MANY problems and didn't correct them fast enough so I had to switch. I lost a lot of data with my old host, so I got fed up and moved.
If you guys need GOOD hosting opportunities... get some membership over at
http://www.HostHideOut.com and post what you need in their reseller forums or whatever you need. It's AMAZING. People will throw these amazing offers at you that you would never think would happen. It's great. Have fun
