Dons Service

I am currently using a really old system called Service Expert EZ that CCI/Triad put out about 12 years ago. I love the program. It doesn't have all the bells & whistles of others but they is exactly what I like about it. It is simple to use & does everything that I need. BUT, it only runs on Window 98. So at the moment I am running a virtual pc on 98 on an XP computer, but would like to get a new computer in the near future. So I have been looking into different management softwares, like Mitchell & Activant service writer. Service writer worked other than I could not go back into the invoices to see information like profit, vendor, etc. Mitchell had too much involved just do a simple invoice. I looked on the RO writer website, but I didn't see any demo information other than having a saleman coming in to show it. Does anyone have any suggestions?
