Are you using GM 7, 6.7SQL or 6.7dbase?
I have found max9 to be a stable-backend product with many features. Yet, compared to GM is it vastly less intuative and cumbersome. Goldmine is a joy to use, the filters, the html email, the easy mail merges (in max9ent you need to set up full blown marketing campaigns just to shoot out one nice html email personalized) , the automation all trump Maximizer 9. In maximizer you need an expensive add-on for automation, and you need an expensive add-on for custom screen design. The only thing GM67 doesnt do is relate companies- it's contact centric. In goldmine you can do calculations and conditionally show fields based on record properties, dynamically, max? no. In GM you can show internet information based on what contact you're on in a special tab, dynamically ( map, directions, stock price, all completely customizable by you). in max? they never even thought of such a concept.So, all in all, Maximizer's pervasive backend is nice and solid, but the UI and the features- they have a long way to go to be modern. If you look at vtiger.com and sugarcrm.com, there's quite a bit to choose from. Unfortunately, Goldmine was bought out and has not added to the existing basic product for a year, but they say things will change now with new owners and money. I'm not sure Id switch at alll if I were you. HTH
