Which agency to choose?

I'm new to this forum and also to open adoption. I know this is a common request, but we are considering a number of different agencies currently and I'd appreciate some feedback (good and bad) on anyone's experience with the following agencies either by private message or email.Independent Adoption Center (IAC)Adoption Network Law CenterAdoption by Gentle CareAmerican AdoptionsObviously, important issues to us are timeframe, estimated vs. actual costs, ease of working with counselors, finalization process, etc... Also, if anyone has a suggestion for an agency that they really liked that would be great as well. We've been agonizing over this first decision on our road to adoption. Thank you so much!
