I'm sure it'll all work out.
While I think scenes are a good acquisition to those starting out I personally get better use from component type collections. I don't think there are any better value collections than your Gary especially where I look at usability and versatility, hey your the only one I've seen with kangaroos and koalas, now we just need some platypus, wombats, echidna, wedge tailed eagles, fairy wrens, eucalypts, zanthorias, mellelucas, Aussie outback ... I could go on with a wish list.
