What's especially attractive at the moment is the price of used lenses. Check out what's available at keh.com (I just bought a 135mm macro from them). That lens now makes a set of four. At these prices I may just end up saving for a used 300mm which is finally really affordable. Up to 11x14 (which is the largest size I've printed) these lenses are amazing. I doubt I'd be disappointed at 16x20 or even a bit larger, but I just haven't made any as yet. I'm sometimes even happier with what they deliver than what I get from my 4x5, albeit I don't have spectacular lenses for it (150 G claron, and a 210 Geronar).

Great camera (P67 with MLU) and an excellent series of superb lenses.
