Has anyone recently integrated Netsuite and Salesforce? If so, what did you use as middleware? I've used Celigo in the past, however, Salesforce is suggesting middleware called Mulesoft, which I assume they have a partnership with. Mulesoft appears to be a very easy to use connector but comes with a hefty price tag

They own Mulesoft, which is why they are pushing it. The price is extremely hefty. Give Celigo a shot - it'll more than meet your needs, especially in the NetSuite ecosystem.

Price is laughable.
