Yes - thank you for your input, it is certainly appreciated.
If I may ask, how much support did you buy / consider necessary?
I'm trying to estimate how much support we will need to purchase, in contrast to the number of issues I posted, which other forum members have been able to help me resolve (i.e. Thanks Neil :))
Our specific use of Arc Objects only makes use of a smaller subset of functionality, and currently does not use any of the extensions.
It is my belief that I am quite close to a working solution and don't want to over-purchase support that will be wasted on one or two issues that I should have been able to resolve on the forums.
