MF was all fine and dandy when I was younger with better eyes and split prism view finder. I may get a focus screen for my 5DII, but other wise, I'm a AF kinda guy.
I find it difficult to MF without a split prism. My film cameras had them and I miss it while using my DSLR.
In portraits, you want a sharp focus on the eye nearest to the camera. If you need shallow Depth of Field, you need to focus with an outer point. (Unless you want to compose with that eye in the center of the frame...:lol
If you are using strobes and can't afford a lot of ambient light in your shot (to focus before the flash) , then you NEED the cross type Outer Points.
And even then, sometimes they 're not (competent) enough.
A 60D is fine, if you can swing it, so is the EF 1.8 MKII at around $100.
