CRM trouble, introduction

We have been growing for the last 6 month in a very healthy way, our customers list include more countries, projects became more versatile. All have been nice but we reached a critical phase in with simply writing tel numbers down is not good enough any more. So we are shopping for a new solution to manage customer`s contacts and projects. So far we had checked Sugar, SalesForce, FreeCRM and ZOHO, the results were disastrous. They are simply to complicated. First task was to simply import contacts list and divide them into some categories. It just took us forever to understand the logic betwen contact and numbers and tasks. We need a simples solution.
