A wholehearted wahoo for http://www.lyonshost.com
, LyonsHost. My husband has a VERY high-traffic web site and we made the switch to LyonsHost several years ago and have never regretted it for a minute. We have a reseller account, actually, which means that technically I could host you but I wouldn't; I'm not that tech savvy on the hosting end of things. Mainly we got the reseller account because hubby's traffic is so huge and I like to play around with different domains.
Jonathan is the owner and here's a true story about him: One time, on a Sunday afternoon 2 or 3 years ago, he called to advise me that there was some sort of a technical issues, what he was doing to fix it and when it would be up. We didn't even know there was a problem. He is AMAZING for customer service. VERY PERSONAL. As long as he is in business, we will never go anywhere else. Ever.
