Craig's right about this of course, but note: lame can be given /lots/ of
options that control the quality and size of the resulting mp3.

It's important you put some thought into what you need; essentially, quality
increases with mp3 size. Just because you've got a 20GB Archos doesn't mean
you can ignore size. Bigger mp3s take up more space on the disk (this is no
surprise to anyone, right?) but they also require more disk reads to play.
Remember, using Rockbox you have about 1.7 MB of memory for mp3 data; bigger
mp3s mean more reads, and more reads mean the battery is used up sooner.

Definitely record in variable bit rate (VBR); this allows lame to allocate
more bits to more complicated parts of a track, and fewer bits to less
complicated parts. Strongly consider using joint stereo; some "audiophiles"
mistakenly think joint stereo produces artifacts in the output, but modern
encoders, like lame, do not.

I use lame at quality High (q = 2), and VBR 2, or Very High Quality (q=0)
and VBR 0, and always use the default VBR method, with minimum bitrate 128
and maximum 320. (I have some CDs of old 78 records (Gilbert & Sullivan!
Yay!, which will record to 128), but I also have some modern recordings of
operas as well (Wagner's Ring! Yay!) so this range makes sense for me.) The
quality settings are probably too high, but I wanted to minimize the number
of times I re-ripped.

With these settings, most of my recordings average out around 192kbps
(although, oddly, Warren Zevon (R.I.P.) recordings almost often hit 224kbps
or even 256 kpbs).

What are you talking about? The only recomendations in
this thread have been for free programs that just like
EAC, also use the free Lame encoder. Since the thing
that controlls the quality of the resulting MP3
encoding is the thing that all the recomendations have
in common... the Lame encoder, and the rest is just a
user interface wrapped around that encoder, the smart
thing to do is pick the one that matches your needs
for features and ease of use. I found FreeRIP
(http://www.mgshareware.com/frmmain.shtml) to be
extremely powerful, easy to use, and packaged with
everything needed in one download, in addition to
being completely free.

Since EAC seems to be extremely popular, I plan to
take a look at that too now just in case it has some
nifty feature that I didn't relize I might want. After
I do that, if I discover that either FreeRIP or EAC
has any significant differences or advantages in my
opinion, I'll report that here so that others can
decide on their own what might be best for their
needs.

The main point to remember is that when you have
several choices that all use the Lame encoder, they
all will give you the same quality encoding, so you
should pick one that has the simplicity or complexity
of user interface features that you desire.
