InmotionHosting specializes in business accounts and offer the Plesk Website Builder for quick and dirty website building and a several options for ecommerce and all that other stuff.
A couple of years ago, I did a little work for them (I have had no connection with them since)--I was impressed with the calibre and commitment of the people there.
They are a little pricier than some of the competition and try to live up to the price differential.
I also do volunteer work with a group who has their site on A Small Orange. We have found their service to be excellent, but we don't use any ecommerce stuff.
I have my own site on GoDaddy. Although a lot of geeks seem to have a thing about GoDaddy, I have found them to be excellent; the few times I've had to deal with support, they have been knowledgeable, responsive, and helpful.
I have heard the folks on the Sunday Morning Linux Review
report experiencing difficulties with 1and1 Hosting, especially when they have tried to move their sites elsewhere, but I have not first-hand experience with them. I can't remember which episode it was that they discussed it, but it was a recent one.
Most hosting outfits offer some type of quick-and-dirty website builder.
