Bryanhod, unless you have many good stations or you are super loaded, jumping on expensive FM-tuners is a money loosing investment. There are many good internet radiostations out there but not as good sound quality as the FM tuners. Most of the audiophiles I know don't listen to radio at all.
I have not heard the 109 yet but the 108 was quite impressive enough to most of the FM lovers.
