PowWeb is probably not the best choice for a high traffic site (10,000 visitors or so a day). If you own a small business and want to start small with some affordable hosting, then PowWeb might be worth looking into.
I have a client that runs a small poetry magazine and they receive about 200 hits a day. They have been using PowWeb for 5 years now and we have experienced very little downtime, none that I can remember in the past few years. They pay $7.77 a month but at the time of this post they are offering a deal – 1,500 GB + 15,000 GB xfer – *On Sale* $3.88/month!
