The bitter experience of Kaushalsheth is described in the above site. He was designing wordpress themes but all his effort went in vein when his host had a blackout. Every hosting company should have a back up network so that no site should be down.He researched the web,consulted the technical advisors and read many reviews. Lastly he
Reached the conclusion that following three companies are best web host in internet.

1- http://www.hostmonster.com/
2- http://www.hostgator.com/
3- Yahoo small business web hosting
http://www.hostmonster.com— It is cheap and it has free set up and domain cost is included. There is no hidden cost. It has a promo offer of $5.95 per month. It has a good supporting staff to support the client.
http://www.hostgator.com— It provides shared, reseller and dedicated web hosting solution. It is suitable both for beginners and professionals. It has 24/7 support service with a 45 days money back guarantee

www.yahoo.com/smallbusiness — It is superb due to its trade name YAHOO. Price is $11.95 per month and it does not charge any set up fee. But it helps in web designing by its experts.

According to my opinion for common man first one is best as suggested by Kaushalsheth.
