InfoPath Dev

I currently have an Excel workbook that contains several data collection forms and 2 worksheets for developing cost estimates. I am going to replace the data collection forms with a new InfoPath form and am trying to decide if I should include the cost estimating features in the IP form, add the custom Office Spreadsheet control to a view or leave the estimateing sheets in an Excel file.

Any suggestions from anyone else who may have some insight would be appreciated.
TIA

How complex are the cost estimates you are putting together? Certainly InfoPath can do calcuations on input fields and secondary data sources etc and put this on your form.

But in general I think you will find that InfoPath is much much better suited to the data collection part than Excel is but that Excel is still going to be better suited for your cost estimates based upon the data you gather with InfoPath.
