Have an extra Flora of Alaska handy?

[aphrk at Msu.oscs.montana.edu]

I'll be teaching some plant id classes in Homer, Alaska this July and
need to get ahold of The Flora of Alaska.  But...the new ones cost
$80!!  Anyone have a copy they would let go for less?  

Or, is there another key I could use that is less expensive.
