Pentax 50-200 vs. a 70-300

Couple questions on this - silly questions, but I'm sort of thinking out loud

Anybody have any comparison shots of the field of view difference between 200mm and 300mm on a 1.5x camera?

Also, any quality assessments between the Pentax 50-200 vs. the various 70-300s available - Tamron, Sigma, etc...

I'm thinking I want an extra bit of length, but not sure I can give up the size on the 50-200... not sure I'd want to keep both lenses around either...
