Let me echo the welcome to the part of the forum for the "out of date, living in the past fossils" or to put it bluntly, "the old farts section." LOL I've been shooting film with a Pentax for almost 40 years starting out with a SV and external clip on meter.
I do shoot digital also but have only had a K100D Super for about 5 months. I think having a good idea of film helps keep from machine gunning shots from a digital. In fact, I was shooting a covered bridge yesterday that I had originally taken pictures of about 35 years ago with my Spotmatic II. Yesterday I was using an MX loaded with Tri-X along with my K100. When I got home last night I was suprised to see that I hadn't taken near as many digital pics as I thought.
Anyway, enjoy your K1000 and let us see some of those photos.
