.NETCF Component that allows entering a signature

I need a component that will allow me to enter a signature on a Windows Mobile 5 device.

I need to integrate it into my .NETCF开发者_运维问答 program. I would prefer it be free (getting budget approval takes so long). (I have seen the "for pay" one by Resco.)

I would need to end up storing the signature in a SQL Server database (it has to be able to serialize). But I don't want the control to do any of the communications for me. I just want it to be able to save to some kind of db compatible value. (I will be saving it in a SQL Server Compact Edition db before sending it to a SQL Server 2008 db)

If anyone has any suggestions I would love to hear them.

The SDF has a signature control in it. And the community edition is free (we've had it long enough the code is probably in the old 1.4 code base too).
