OPC Client development for PLC tag monitor

I am trying to create a VB .net application that monitors an OPC tag that is selectable by the user. The user chooses the Machine, ProgID, and ItemID. THe software will monitor this tag

I know there are a number of VB.net OPC client development packages out there that should help me with this. I have purchased the Software Toolbox Top Server Extender to try and go that route, but i am open to something else if it works.

My biggest issue i have encountered is the lack of sample code and guides to help me do this.

Any advice?
