Rodney,
"Martin" is available from at least one US source, NAFEX's own Bill 
MacKentley, at St. Lawrence Nurseries, in Potsdam, NY.
http://www.sln.potsdam.ny.us  - look under "Juneberries"

Bill has one of the largest collections of Amelanchier selections in the 
USA, but doesn't offer all of them every year.  I got Martin from him a 
couple of years back, but I'm not certain it is still surviving - not an 
indictment of plant quality, but of my stewardship.  The named-variety 
selections he offers are tissue-cultured specimens, and relatively small, 
but they've done well for me in the past.
I didn't get around to ordering from him this year, but see that he was 
offering "Lee #3", which, I've heard, is the best A.alnifolia selection yet.
