Yeah, OP, I think there's a progression involved here. I had 9 lenses and a 1.4x at one point, many of them expensive, now I have 6 - all under $1000 - and a 1.4x and wish I could have less. Conversely, I have two 580exII's and am sorely in need of another. The transition I'm talking about is where the image becomes the ultimate goal and the equipment - as long as it's up to task - becomes secondary. The exception to this I'm finding is lighting. One can never have enough light...
