given a choice, i always choose an A lens over a non-A lens. the functional enhancements makes sense even if it costs a bit more.

That's good price already. I think A 50mm f1.4 should be around $200+

if A 50mm f1.4 is around 200+, then a 2nd hand DA 35mm f2.4 also can be a good candidate. (at a wide focal length)

If you could find an M50/1.7 for $40, I'm sure you can find an A50/1.4 for around $100 (about 2.5x of an M50/1.7). Just keep looking, and good luck ;)

Can also get the A 50mm f/1.7 which is a little cheaper and allows every exposure mode to be used and for the exif info to be captured.

Get the 'A' version over the 'M'.
You retain camera control of aperture, Av mode and its conveniences, PTTL, EXIF data.

'M' lenses are a bit smaller and nicer in build though.

Ok!! I will try my best to find it. Ooh, last question:

A50 f1.7 is comparable to M50 f1.7 right?
A50 f1.4 is just slightly wider aperture right?

I have owned all the 'A' and 'M' 50mm (from f1.4 to f2).
Still have all the 'A' versions and a M50/2 (though I like the build of the 'M' ones so much more).
No difference in sharpness in the center on any of them at the same f-stop.
Never bothered to compare edge sharpness.
Use a hood to cut out loss of contrast is important as well as accuracy of focus.
