I looked at them before i bought my hosting with siteground, they looked good but i realised that Business or Developer package you did not get any MySQL databases, which will be a real problem if you want to try and have a forum or your using a portal like phpnuke etc.
Take a look at www.siteground.com their offers are really good and the support is 24/7 and you get a reply within 15 minutes if you need help.
Have you bought from them yet? If you are going to please could you go to www.loxzclan.com and in the bottom left corner click the link i have to them. As i reffered you to them i get 3 months free hosting
With siteground are you restricted to using their site builder utility or can you say code a webpage by hand and then simply upload the file to the server?
either, doesnt matter. I just installed a portal and went from there. You can use dreamweaver or any software like that to make your website and upload it.
I am currently using 1 and 1 for my hosting. So far it is been OK, no problem. I have 4 websites hosted by them. I have been using them for about 2 years now.
