Thanks everyone for your input. I actually haven't used an af lens, and am worried that I'd be going to manually focus it anyway if I'm shooting in less than ideal situations, which I do a lot. Also, since I wouldn't be gaining much in speed, then it'll just be a redundant lens in my collection. I'm going to stick with the trusty A f1.7 lens. I have actually grown to love to manually focus, even though it does mean I have a percentage of a bit not totally tack pictures, for which I take a couple quick shots of what I think is in focus and a little turn more especially for landscape photos. For those who have problems with seeing totally sharp in the viewfinder, I stand by the tenpa 1.36x viewfinder magnifier on ebay. It has drastically improved my % of hitting the sweet spot. And that .36x magnification makes a lot of difference to me when not zoomed in.
Because of you all, I've avoided LBA, even though I think the FA is a good deal, especially if it was like new upon inspection. You are right in that I'd be better off putting the money to better use by getting a good wideangle lens, and I also would rather not deal with resale unless I have to.
Thanks again!
