Open ERP - anyone using it?

Hi guys, I recently discovered OpenERP and currently I am playing with it - so far I am very pleased. its quite difficult to install/configure, but by the looks of it, its a very powerful solution. I am yet to finish the setup of it for a company now, but it seems it does support multiple ledgers and I although I havent deployed SAP before, I have a feeling it fares quite well against it. and the best part of it for me is:

- Free
- Integrated CRM
- stock/purchasing control
- multi-currency
- installs on both - linux and windows

the software has hundreds of available free modules, such as manufacturing, project management, servicing etc, yet I dont need them in this setup.

Either way, would be great to hear if anyone is using this and how are you finding it?
