I forgot about that one. SpreadsheetGear one is $999 and comes with 1 year phone/email support, the Infragistics one is $995 but if you want the "priority" phone/email support it's $1490.

They both have evaluation ones you can download. I don't know anything about SpreadsheetGear but everyone I've talked to that has done business with Infragistics seems to like the company and their products.
Sure seems like a lot of $ though - surely there is a freeware opensourse one somewhere...geeeze.
