I've got domain appraisal software that I'm giving away for $5. It's got full resell rights also, so it can be sold to your clients. If you're interested you can paypal from the link, I'll email the software to the email address paypal sends me.

(Note: This is also the software we use to give free domain appraisals, which helps drive traffic to your site)
software only works for .com .net and .org domain extensions.

PRServers please PM me.

Not sure if I mentioned that this software comes with full resell rights, you can buy it for $5 and sell it at whatever price you see fit to your customers. It's a great deal.
