Calgarian,
In my experience, MM cartridges are far less susceptible to age related degradation than MC, so your K9 may be just fine. I'd stick with a solid state phono preamp for now, and stay under $200 used, which would cover most of your list. If you want to buy new, the Cambridge is a steal here:

If you taste vinyl and like it, you'll want to replace your whole analog front end to bring it up to the level of the rest of your system - it's very seductive!
