We have tried a few web providers in the past but settled on cpanel hosting from our current provider. eukhosts if that makes any difference. Cpanel gives excellent solutions for things such as shopping carts and forums with an instillation being just a click and some basic info. We use the ZenCart install quite a bit.
Also AWStats can be very useful and the way they are laid out means we can send monthly reports to clients about the performance of their sites...which they can actually understand!
