I used E2 for 2-3 years, up through 2003. Not what I had recommended, but it was cheap, the owners swallowed the hook. I did a lot of quoting, routings, purchase orders, etc. It's ok if you don't try to use it to full capabilities. We made a fairly complex product line and bill of materials and reports weren't there(2003) We got lot's of promises about fixing reports yada, yada. Never happened. Hopefully they fixed it by now. I liked Visual Manufacturing from Lily software. A $30k+ sysytem, but, they had a bare bones version for $2500 a few years ago, I haven't looked into it lately. I could never trust my evaluation of Job Boss because they only hire beautiful girls.
How about some links on these other ones being mentioned? What are the price ranges?
