Hosting a mutlisite account--alternatives to Psek

I have had a week of nightmare experiences with Psek. There customer service is awful. I just sent a message to cancel my account with them. Can anyone recommend a reliable hosting company that can set up Multisite properly with the subdomain structure recommended by WPMUdev?

So frustrated...wasted days of time wrestling with them to fix a problem they created only to have them reinstall multisite...with the same problem. Grrrr...

BTW--WPMUdev staff: I tried the "search" function in the community section to see if this topic had already been discussed, but the search doesn't work. I even searched for terms that were showing up on the community featured topics page and nothing came up. Just a heads up that something might be wrong there...

Thanks in advance for any advice you can give.
