I'm not impressed with Keepster. I really don't like the 2-3k message limit for adding imessages to a Keepster folder -- adds more steps than necessary for creating a project. Also, I hate the 800 page book limit because it's really not enough space (I am trying to make a book of only 1 year worth of texts between my fiancee and I, so not multiple years). Lastly, the backup only has texts from the first 4 months and the last month, with months 5-11 completely missing (tried twice). Not sure if it's an iTunes backup issue or a Keepster issue but it's really frustrating.
