Maybe you need to look at this or if you have, look again?

I'm not selling K5s, I'm not even a fanboy, I have some problems with Pentax really...(who doesn't?) but I look around every day and read tons of owner reviews of the various new cameras and a lot of what I read is not encouraging......even for cameras costing almost twice as much. Most of the problems I see are non-existent in the K5, and then when you start looking at the IQ, it just isn't anything more special that what I get from my K5 on a regular basis.....it just isn't!
When I got my K5 a year ago, I felt like it was pretty much my dream camera, and nothing has changed my view since then. If there is something better out there for the low price now being offered...or even as good, I haven't seen it or anything close to it. I see more expensive, I see bigger and heavier, I see smaller and less capable with a ton of faults that are not acceptable to me, but better......nope, still don't see better.
That's how I see it, you have a connection like I do, look around, you are going to see the same thing I've seen. If you are serious about upgrading, this looks like the time to do it to me. All those great Spring and Summer shooting opportunities are almost upon us, and the K5 can take advantage of every one of them, I guarantee!
