In addition to the other vendors and the Classifieds you might want to look for a local mentor.
I found a local contact when I offered to PIF some Feather Blade samples in one of the other forums.
We ended up trading different "Feather type" razors, then conventional straights.
He loaned me a used Hart that he had brought back to life - that exposed me to Hart, 1/4 grind and square points - and I'm the better for it.
I loaned him some W&B's, older slants - and he was glad to try them but not his cup a tea...

Like just about everything else, its all very YMMV.
Some of us never deviate from a particular type of razor.
Other (yours truly) change as they learn.
My early exposure to the square point was a disaster for instance.
Now I can't imagine trying to shave and trim my Mo with a round point - my regular shavers are Square, Spanish, Barbers Notch or "American" (Ralf Aust)

Smooth Shaving...
