I have 2 hosting accounts with Soholaunch.
I separate my company accounts & backups from my client accounts, so if the client servers ever go down, my site will still be up for support.
One is with Host Doggy. (hostdoggy.com). Their service/response times have been fabulous. The respond to almost every inquiry within the hour - even on weekends and their prices are very low. I believe my account is $8.99/month. He has also been very willing to get in touch directly with Soholaunch on technical issues which has been very helpful.
My client accounts are on VARhosting.net. I chose them becuase they have live chat support for my clients. I have been fairly happy with them as well, but haven't had much interaction with them specific to soholaunch.
I do have questions for anyone else using soholaunch... I am trying to decide whether or not to offer it as a standard offering to my clients. I really love the capabilities, but it seems very buggy. Does anyone else have an opinion about it?
