[Koha] Resistance to Acquisitions

Hi. We are just in the process of migrating from Dinosaur Dynix to Koha, thanks to ByWater Solutions. An acquisition module is not a part of our old system. Nicole Engard is in town training us and went over acquisitions today. There is a surprising (to me) amount of resistance toward using Koha's acquisition. They seem like they would rather continue the way things are with spreadsheets and such. Which got me wondering... How common is this? I mean, how many of you folks out there among public libraries do NOT use Koha Acquisitions? If not, why not? If you do use it, why? Just curious mostly, but also I would like to have something from other libraries to share with my colleagues, pro or con. Thanks in advance. Jim Maroon
