How about Alibris books.

Here: [link=http://www.alibris.com/search/search.cfm?qwork=%2D96878170&wtit=A%20Tradition%20 of%20Excellence&matches=2&qsort=r&cm_re=works*list ing*title]A Tradition of Excellence[/link]

If cost is not an object, it looks like a good quality copy can be had for $169.97 CDN.
I've purchased many out of print books through them.

Cheers,
