Mechanical Shop looking for feedback on PO & Inventory Control System Management using SAGE 300 ERP - 2014

I am looking to make contact with a similar service company that is currently using the SAGE 300 ERP PO & Inventory Control Systems. We are using SAGE 300 ERP AR, AP, & GL  but are using a 3rd Party software for our Inventory Control System and Excel (manually) for our PO System.  We are looking into integrating all to SAGE 300 ERP.  I would like some feedback on how well the SAGE modules worked for the dynamics of a Mechanical Shop. Any recommendations, advice, or issues, as well as any contact information for any one who may be willing to discuss more in detail, would be greatly appreciated.

Thanks!
