Not only that, but if your selling saas, people are younger/savyer (sp?) and are buying almost exclusively over the web. When that happens, if you are a resellers of somebody elses Saas product, good luck with differentiating and it not become something sold on priceshopper.com
Unless you have ranks of decent consultants based out of a low wage country, you won't get the rates you need to build and grow a business.
I'm still waiting to hear from 1 var who's making good money and growth on net new names doing a pure saas solution after the 1st deal they did which caused them to sign up.
