Last year I bought some aluminum wire in coils like you describe.  I 
think it was a company
in Ohio and may very well have been Malinco.  Anyway, they had a 50 lb 
minimum and charged
something like $3 and change per pound.  This is way cheaper than 
McMaster.  I wholeheartedly
agree that alloy 1100 is the hot setup.  BTW, did you know it also is 
the most corrosion resistant?
The stuff I got was annealed to practically wet noodle consistency :-).  
Wonderful to work with.
