I'm also on paper records ... It's getting voluminous (up to three binders now just for snake records) and I'm planning on switching to electronic next year when I move.
I just downloaded the trial version of Vyper and fiddled with it for awhile ... So far I love it, so I'm leaning towards going with that one. I really like the way it's set up; very thorough. I like the interface as well. Everything seems very well integrated.
I'll have to look up Kintracks ... I'm gonna need a separate software database for chinchilla records. :P There's one out there, but it costs $65 and I don't think it's been updated since 1996 ..! :O
