Try this
<cfset price = REREplaceNoCase(testString,'Our New Price: <font
[^>]*?>\$([\.,0-9]+?)',"\1")>
<cfoutput>#price#</cfoutput>
This will ignore any attributes within the font tag so you don't have to
worry about them changing... It also sets your price with a single <cfset>
rather than 2

Depends on your requirements... Do you need the image specifically which has
the ALT attribute of "Operating Systems"? If so, you might try this:
<cfset temp = REREplaceNoCase(testString,'(<img [^>]*?alt="Operating
Systems"[^>]*?>)',"\1")>
<cfset src = REReplaceNoCase(temp,'href="([^"]+?)"',"\1")>
The first regex gets your image tag, then the 2nd regex gets the src
attribute out of that. This should work even if they move the alt tag
around...
