A buddy of mine works at a bike shop in my hometown and can get me a Trek 4500 (limited sizes) or 4600 (any size) at just over cost to the shop.
I really like the Trek 4500 in Blue/Aluminum and the components and such but he can not get it in 18 nor 19.5. I can however get it locally for the normal price you would expect to pay (much more than my buddy could get it for me, if he could in fact locate one).
He can also sell me a 4600 at just over cost. I like the look of the 4500 better (color wise and although not a high importance factor, you need to like your bike and the way it looks!) If I could see the following bike in the Aluminum color it might help me decide!!
