What is your experience level with reseller accounts.
If you have a lot of experience and won't require technical support I would recommend http://www.tronictech.com/ They are the budget division of Ion Web services.
Or you could try out Ion, http://www.ion-web.com/ if you have more requirements in the tech support area.
Thanks guys. I gave up on dathorn. I've had a reseller account for the past 6 months but with a different host. I just didn't like their servers too much - always above 80% on memory and close to 100% on cpu therefore the speed of the sites I hosted wasn't great. I was interested in dathorn due to their reputation of being reliable but my first impression of their customer service really put me off. I myself work as a tech support rep so I know the difference b/w lackadaisical and good service.
When we were a reseller we used Host for Web for some time, then upgraded to their VPS before moving on to our own hardware. They have an active community forum which I am still a member of so while I don't have any reseller sites with them I know they are still not having issues and their resellers are happy. They run high-end specs on their boxes and don't overload them, and their support is absolutely exceptional (although you may not need that)
When I was there we had great uptime (other than scheduled stuff) and they are on a good network in a quality datacenter (Equinix). Server loads spiked occasionally but that was rare, usually were consistently stable & well within reason & memory wasn't overtaxed.
Having not used them for reselling in a long time I know they have upgraded and am not sure but I believe they are running resellers on quad processor boxes (Intel-but maybe dual since 1 HT can show as 2 if someone doesn't know) with 8GB RAM (from what one of their member's said in a post there).
