Could anyone recommend a popular and highly supported open source ERP system?

Our business is currently growing and we're beginning to feel the need for an ERP system. After looking around it seems there are an overwhelming amount of options and its tough to weed out the good ones. Preferably I'd like something that's open source, popular, and customizable. Can anyone recomme

There a few good Open Source ERPs to mention here with their exact specifications. You can choose any one of them as per your enterprise needs.

• Compiere - ERP & CRM solution for small and medium-sized enterprises
• Apache OFBiz – Enterprise level software framework
• ADempiere – Business solution offering ERP, CRM & SCM functionality
• Dolibar - Compact ERP & CRM
• OpenBravo - Designed with broad business functionality
• WebERP - Complete web based accounting & ERP system for SMEs

Just to add to the list OpenERP seemed great when I was checking these out. The combination of online and desktop client (all opensource) pushed this one over the edge for me.
