I have been doing some research but can be very time consuming, and wondering if anyone has some feedback.

I am looking for a CRM or system for tracking my domain sales and potential sales. So for instance I can log in all the interested parties or potential buyers for a domain. And then update it is with notes, follow ups, rejections, offers, etc..

Most of the CRMs I research must have like a few different products and then have lots of contacts for those projects. Domains are like single unique products with multiple potential purchasers.

I am looking to try:
pipelinedeals.com
futuresimple.com - base
highrisehq.com

Haven't looked at Salesforce.com yet, heard it is a pretty complicated.

Any feedback is appreciated.
