I would concur. After much Googling, we decided to keep track of our books using Quickbooks. I'm not a big fan of their business practices, but there is some peace of mind when going with a de facto standard: support and a huge knowledgebase. If you have a question or problem, there is a good chance that someone has answered it, or provided an add-on module to address it. If a great PM module comes down the pike, there is also a good chance that you can export the QB data in a format that the new PM can likely assimilate.
We did not want to introduce yet another proprietary moving part into the mix.
