anybody successfully using any Cisco 3750's with the C3KX-NM-10G module working in NTA

anybody successfully using any Cisco 3750's with the C3KX-NM-10G module working in NTA (Netflow Traffic Analyzer). We are trying to avoid buying routers at our satellite locations simply to gather Netflow data. Cisco's documentation reads that with the C3KX-NM-10G module, netflow data can be captured from the Cisco 3750's. Would love to have confirmation before we purchase 8 of these modules and hope that it is supported in NTA.

thanks!
