Is the pentax k x worth buying used?

Yes, I think the K-x is a good buy used. It came out in 2009, so it's an older body, and that's exactly the kind of camera the buying used page recommends: often most of the camera for much less money. You get a 12.4-megapixel APS-C sensor, stabilisation built into the body, and four AA batteries, which is handy when you're away from a charger. Old batteries lose capacity, so budget for a new genuine one.

For an everyday kit, I'd start with the Pentax smc DA 18-55mm f/3.5-5.6 AL WR. Add the Pentax smc DA 50mm f/1.8 for cheap, lovely portraits. If you want reach for wildlife or sport, the Pentax HD DA 55-300mm f/4.5-6.3 ED PLM WR RE is a sensible choice.
