I have an *ist DS. The K100D is a good entry-level DSLR, especially with the built-in image stabilization. The kit lens is actually pretty decent compared to other kit lenses offered by Canon or Nikon. For quality macro lenses, you'll have to spend a decent amount ($500+) but as attack11 mentioned, some of the older Pentax glass are excellent and the third-party lenses are decent. For more specific info or to ask questions, check out Pentaxforums.com (I'm a moderator over there.)
