What reliable web hosts offering e-commerce hosting accounts do you know?

I would like to make a notion on the e-hosting market. What are good web hosts?
Need over 20 gbs of disk space.
What can you say about QHoster.com services?
I have also found Dailyrazor.com web hosting solutions.
One of my friends recommended me to try these guys. What are your points on these hosts?

Any other e-web hosting providers? What host would you choose from these two?
