Next to my 80, I use the 150 the most, and the 250 only about 1/3 as much as the 150.
Thanks to all for advice. I've ordered a 150 CF from KEH.
If you can't rent one, KEH is the next best thing. There will be no hassles and no questions asked if you get it in and decide you need the 180 instead. Great folks to deal with.
