arcpy - ArcGIS Conflation Tool Recommendation or Custom Script for Comparing Points

Can anyone recommend conflation tools for ArcGIS Desktop (10 or 10.1, paid or free) or a scripting outline / procedure (or just a script) to have a technician efficiently process the following rules?

We need to compare and update 2 points of interest (POI) point layers, let's call them MasterPOI and ComparePOI. Aprox 30k points in each. The rules for a technician would be the following:

1. Find any ComparePOI points within a ~1000m of MasterPOI.


2. If a ComparePOI point has a better location or a better description (using their human judgement), update MasterPOI with either location or its description field.



3. Separate step maybe -- then any ComparePOI point not used to update MasterPOI, simply add it to the MasterPOI. Most points would fall into this category. (I'm thinking just put a flag on a feature in ComparePOI when #2 occurs.)

I could script it myself eventually, but wondering if someone has some experience they could share
