I have now used PipelineDeals in two different organizations and could hardly be happier. The interface is simple, but the features are very sophisticated and customizable. We have a unique industry in terms of sales cycle. So, many "canned" CRM products just don't work. But, Pipeline gives us the ability to adapt the system to our needs rather than forcing us to change how we do business to fit the application.
I highly recommend it to anyone who is managing a sales force of one or one hundred. On top of it all the up front support in getting the system up and running is tremendous. Again, excellent system, very good support. Couldn't be happier.
