I just bought a Pentax Digital (used) and did so because I wanted something which did one thing well- measure light. I still have my Sekonic L-558, but it was a PITA to use with all the bells and whistles. If you don't mind carrying the owners' manual and consulting it to figure it out, a Sekonic is fine- think of it as the metering equivalent of a sophisticated DSLR in terms of menus. I wanted to take a reading quickly and take the picture, not try to remember which menu to be using, what the numbers indicated, which button to push, etc. The Pentax does its job well. YMMV.
