And thanks to Glen who pointed it out for me, I just purchased a copy of
Swartzlander's 1976 edition for under $8 on half.com. Thanks again Glen!

Amazon provides a marketing/communications service to their
associates, but the size of the market for each rare used book is not
big enough to force price equalization on an economic theoretical
basis.
Today's Amazon query gives 4 copies of Swartzlander from $87 to $113.
You never can tell how long they will last, and if you don't find it
one day, it may show up another. Amazon provides access to a database
and the content will vary.

Well, I have to admit my Blahut book purchase slightly pre-dates Amazon
selling used books. I did get a very good price on a copy in "very good"
condition. I believe I finally got it through Alibris. I've had two
experiences with Amazon used book resellers. One turned out not to have
the book, and wasn't able to get it. The other went through flawlessly
and I had the book the next day. On several occasions I've noted that
I could find the book elsewhere for a fraction of the amazon used book
price, sometimes even new. I don't know what that is about. I'm still
looking for a copy of E. Swartzlander's Computer Arithmetic, which is a
compilation of reprints of important DSP papers from the 60's and 70's,
including a reprint of the original Volder paper on CORDIC.

I've also had a couple of good experiences with amazon's resellers.
I found the aforementioned Blahut book in good shape for $50
and a mint condition Crochiere & Rabiner Multirate book (the original
green hardback) for $70 -- less than I could buy the cheap xerox copy
they sell nowadays.

I've never had that problem with Amazon. Their tools plug right in to the
inventory databases. If there's one business that's been entirely changed
by the internet, its the used book business. When you click "buy" from an
Amazon bookseller, they'll have access to the book-- don't worry about how,
but you'll get it.

And if you contact those resellers, you'll likely find that some or all
of them don't have any in stock but will do their best to try to get you
a copy through their network of other used book resellers.

Take a look at kissfft.
http://sourceforge.net/projects/kissfft
It does mixed radix FFTs on various fixed or floating pointdata types.
160 is no problem 160==5*32. Kissfft has hard-coded butterflies for
2,3,4,5, (as well as a generic DFT-style butterfly for larger primes).
It has been used on a wide variety of platforms. You mentioned using a
DSP. Which one? Is there a vendor-supplied FFT library that would work?
Looking back over your post; it is not clear to me that you really
*need* a 160 pt FFT. If you don't need the exact frequency resolution
that comes with N=160, but rather can use N=256 then you have more
options as far as FFT libraries that are radix2 only.
Although if the library you choose does support N=160, then it will
probably be faster. (It is so with kissfft and fftw).

Yes, another very good source...if you can find it. it can be difficult
to find a copy either in the library or for sale. It took me over two
years to find a replacement for my personal copy when it disappeared
from my bookshelf at a prior place of employment. The usual used book
places sometimes list it, but then when you go to buy it they reply that
they'll notify you when they find it. The local state university
library showed one in their inventory, but it could not be found when I
tried to check it out about 10 years ago.
