I own the K1 and recently tried the KP at a camera show. I love my K1 and loved the KP too. KP is much lighter and a very capable camera. My thought on rentals is this. If you know you want to commit to the Pentax platform then do not waste your money on a rental. Just buy into the system. As far as camera choice (K1 vs. KP) if you do not need a full frame, then get the KP. It has plenty of resolution and capabilities to last you a long time. As to lens choices, I would get the 16-85 or the 20-40 for starters. It would take care of most of your shooting in a wedding and any other situation. You can always add longer or shorter lenses later. As far as flash choice, I have the 360 the 540 and a Metz 52. I like the Metz the best of the bunch. They all work just fine so you cannot go wrong with any of them. Your budget will dictate what to get. Just my two cents. I hope it is of some use to you.
