Cast Iron provides 2 connectors for Salesforce APIs (Transactional and Bulk). It makes integrating with Saleforce very simple and relieves you from having to learn/deal details of the API and focus on the task at hand, integrating.
As far as trials, no public trial links are available but you can contact Cast Iron and request it.
