CRM for real estate investing needed

I am a real estate investor. I have been needing crm software for my real estate business and I would like to get software that is similiar to the one at www.realinvestorsoftware.com. I don't know if it will be a desktop application or web based. I would like prices for both and what the pros and cons of them would be. Please ask any questions that you may have. ## Deliverables I have had numerous scripts made for me but nothing this "involved". While I don't know how much something like this would cost,I do have a couple of friends that know software well so please just be honest with your quote and not try and take advantage of me as I will get their opinion on what your bid is for this. I want this product to be smooth and reliable.
