Mouser also has a non-surface mount part (511-4049U) for .44. A surface
mount part is if you imagine a standard part wihout any "legs"... thus
instead of putting the legs in holes in the PC board, you solder directly
on the surface (a little tricky). They're very compact, but not really
for use by hobbyists. Feel free to correct me if i'm wrong in my
understanding of this.

Nope, they sell them in singles, too, although they're $.09 when bought in
quantities of less than 100, .02 in quantities of more than 100. So buy
100 anyways if you need common values like 100k or 47k, you'll use them up

I find digikey a little better than mouser honestly.. online ordering is
quite convenient... altho for some things (knobs for example) i still go
with mouser. http://www.digikey.com.
hope this helps.
