Gosh I love this site! I post, take a nap, and then 2 hours later BAM...9 replies...

You guys are great. Anyway...
After reading your comments, I'm kind of leaning toward a hitch setup. I probably will ride alone most the time so I wont have the help of a friend to lift the bike. (I'm 5'8"). I do have running boards but actually now that I think of it...I live in a very hilly area with low trees and I don't want to risk getting my bike stuck in an oak tree or something.
So far this is what I have (open to corrections if you have any):
Roof Rack
-versatile
-sturdier mounting
-not as easy to mount bike
-does not need to be removed
Hitch
-weaker mounting that can scratch
-not versatile
-easy to load
Mainly what I'm looking for is cost and convenience, and I think the Hitch would do it for me.
My bike is already pretty scratched up so "Two Load Arms through the bike frame " wouldn't be a problem for me. Although it seems like a Saris Cycle type mount would be sturdier and nicer on the bike, it's a little costly for me. Has anyone had experience with the "two load arm" hitch racks? How much would I be sacrificing if I went with the load arms instead of a saris style rack.
Expat, do you have any problems with your hitch? It looks very simple and functional and the rubber straps would probably eliminate scratching, I'm guessing. Still, I'm not sure I want such a big rack though.

Do those come smaller? I only need to carry one bike, possibly two.
As for versatility, the only "sport" I might need the 4r for is snowboarding, and I can stick that in my trunk.
How about
two bike thule
or
swagman
This looks a little cheapo but has anyone tried these?
bell racks
Any other suggestions will be very helpful. Thanks for all your help!
