#2. Enom customer service is BAD. I mean it. OpenSRS support is sometimes slow, but you get a reply in a day or two. With Enom, you can sometimes forget it 
#3. Enom site is sometimes slow a bit..
#4. I like Enom's API more than OpenSRS. It's more friendly and easier to code and it's not that heavily dependent on PERL libraries/modules, plus doesn't require high skill in coding (plus, you can do API in php/c/java etc, but with opensrs I believe you are limited to their perl open-source version (I heard there are another freewares as well)).
Well, but price matters.... I think.
Hosting3.com !
You are exactly right!
However, I think you've got to think, here is figures for eNom.com:
Total Domain Name Registrations (in all TLDs): 1,236,181 as of 8/23/2002 7:18:40 PM (PST). *1
Total Number of Hosts in eNom's DNS: 1,964,348 as of 8/23/2002 7:18:40 PM (PST).
Net new registrations per month for .com .net .org TLDs: 97,814. *2
Average DNS queries per day: 40 million. *2
Average emails forwarded per day: 518,000. *2
Resellers: 7,772 as of 8/23/2002 7:18:40 PM (PST). *3
Active Resellers: 3,587 as of 8/23/2002 7:18:40 PM (PST). *4
Resellers using eNom's API: 3,074 as of 8/23/2002 7:18:40 PM (PST). *5
With 3,587 resellers are active, they sold in the past 3 months. If you get accounts directly from eNom, youv've got to deposit a lot, if you got it from resellers, it may cost different.
But most member in this forum know that the lowest cost is US$6.95 and there is no difference between each reseller. If you are a talent programmer, you may earn extra but making the interface difference from eNom's default interface. Otherwise, it was very easy to be differentiated by customers who just browsing the internet to get the lowest price.
I my personal experience, it is hard to a eNom's reseller, I charge more for providing better services (prompt answer of email) but customers seem just want to seek the lowest price. So they went to 8.48, 8.75, 7.95 or 8.97 domain providers.
While you are a Opensrs resellers, every one know that the cost is higher, the skills (PC) is higher, so it cost more. Just add more free services (i.e. forwarding) it catch more clients.
eNom.com most of the time loss my questions, and they need you to trial and trial to learnt how to use their services before telling the customers how to do.
The problems is that my customers have less computer knowledge. I sometime feel hard to answer their email. I email to eNom to get help but they may loss my question, I think.
I will suggest go the enom's web page and get a feel of the API first before join as reseller.
On the other hand, if you have a lot of clients, it will be a problems to get them transfer their registrar from Opensrs to eNoms, right. Got to think about the schedule before transfer them to eNom.
This is my little ideas. They may not be all correct.
