@MarkChinsky My honest opinion is that there is nothing special about Salesforce for the SMB market. In fact, you pay a high premium for the name recognition. Here's a quick back of napkin comparison on pricing:
SFDC (5 year, single user): $7,500
Sage CRM (5 year with GOLD M&S): $1,789
You *might* be able to get away with the lower version of SFDC which is: $3,900 for 5 years.
Still ... is it worth twice the premium? No way.
