Spring cleaning, advice needed (2 parts)

I've decided to do some spring cleaning.

I'm getting rid of my spotmatic and takumar lenses.

I simply love the convenience of my Super Program more.

Anyways, so i'm trying to get lenses that I can use on my K10D and Super Program.

I already have a Pentax A-35-105mm f3.5, recently acquired Tokina 17mm f3.5 and now i'm looking for a good 50mm fast prime.

FA 20mm f1.7
or
F 20mm f1.7

I checked out a bunch of comments and decided that I want one of these two.

is there much of a difference between the two?

Advice Part II

Here's what i'll be selling later

Spotmatic IIa + carrying case + SMC takumar 55mm f1.8(all excellent condition)
Super-multi-coated-takumar 28mm f3.5 (with case, no hood, very good condition)
Super Takumar 135mm f3.5 (with case and hood, excellent condition)
Original Pentax M42-K mount adaptor

Any suggestions for pricing?

5 choices

Pentax FA 50mm f1.4
Pentax FA 50mm f1.7
Pentax F 50mm f1.7
Pentax A 50mm f1.4
Pentax A 50mm f1.7

Which would you recommend?
FA50/1.4 by far. There is no other. And it focuses manually too.

Take a look at COMPLETED LISTINGS on eBay. Read'em and weep. Those are fine lenses, and eBay is awash with them (and Spotty's too). I have a couple extras of those, but I won't sell them now because they just won't get worthwhile prices.

Between the F and FA 50mm f1.7, there is no optical difference, the only difference is cosmetics. For your purposes, note the F has a ribbed plastic focusing ring and the FA a smooth rubber focusing ring. The FA is harder to find (and thus tends to command a premium). If you're going to be largely using it with your Super-Program, then there is no need for an AF lens (in fact, it's better to have a MF lens as the AF versions don't manully focus nearly as easily as their rings are geared for AF usage)--just get the A50/1.7, which will be much cheeper.
