Anyone offer domain registration from their site? ...

What do you use? I have heard of Dotster and Alldomains.com both offer Reseller Systems for Domains.

Any others that we can add to the list?

If you use any of them, how are they?

Thanks.

We use opensrs.org from Tucows and have been pretty happy with them.

Yes, I have heard of opensrs. I hear they are very good, but the initial investment does not fit my budget.

Ive heard opensrs is good.
We use bulkregister.com
and have no complaints at all.

I've used Bulkregister.com ( A division of Alabanza.com ) for several years. The initial investment is $79.00 and domain registration is $12/yr ( less if you register more than 50 in 1 month ).
There are cheaper ways to go, but the support and control interface are excellent. I can register a domain and it points to the server usually within 8 to 24 hours.
I can't compare their service to others since they are the only ones I've used, but I've been very happy with their services and the support has been fast and excellent.

I also use BulkRegister, and I have used Alldomains.com and Registerfly.com, and I started to use godaddy.com.
I have to saythat BulkRegister is by far the best I've dealt with.
Alldomains support is terrible, and the representatives seem to know very, very little about the business. They are easy to reach, but hard to get results and are anything but timely.
I realized within about a day that Registerfly.com was a reseller for enom.com, and they sucked to say the least.
godaddy.com looked very inticing, but I offered them a business proposition on their high setup fees, and they accepted...after filling out all forms and registering a few of my own domains, they called to tell me that their "founder" over-rode the decision. First they renigged, and second, if the "founder" gets involved in every $500 issue, I can't imagine they are a very responsive Registrar...I know that most of the small resellers are individuals or small companies, but a Registrar? Give me a break!
BulkRegister is great service and a good price. Enough said. ;)
