Add-on Components for SSIS

I've just discovered a new 3rd party add-on for Integration Services by Ivolva.com.  There is a SSIS wizard http://www.ivolva.com/ssis_wizards.html which simplifies the process of creating a custom task or data flow component.  There is also the Extra Sort component http://www.ivolva.com/extrasort.html which apparently provides enchanced performance for sorting large data sets.  I'll take a look at these add-ons and post my comments later.
