Data Shuttle Price and features



Can someone tell me the monthly subscription fee of Data Shuttle please?

The only feature I expect to accomplish with Data Shuttle, is to auto-update the dropdown column values, by linking the given dropdown column to another column / sheet of Smartsheet. By this I mean I will not be importing data from any external source, but from within Smartsheet only.

Furthermore, with my requirements so specific and limited, I would expect Data Shuttle to perform the said task in an absolutely robust / foolproof manner!
